FMEDESKTOP-11429 Selecting feature types to read for a Single Merged Feature Type reader using the Feature Types to Read parameter in the Navigator pane causes "Failed to Retrieve Feature Type" error.  Enable Prompt for User Parameters in the toolbar or through the Run menu and select the feature types to read through the Translation Parameter Values dialog.  2021.0 b21302 2021.1
FMEDESKTOP-11422 User Parameter for Choice missing the option to import values from Reader or Writer formats Upgrade to FME 2021.1 build 21554 or newer 2021.0 b21302 2021.1
FMEENGINE-70052 "Bad variant access" error when renaming numeric attributes. Typically this error has been seen when using the AttributeManager but could occur with the AttributeCreator or other related transformers. Upgrade to FME 2021.0.3.2 build 21332, or FME 2021.1.0.1 build 21610 or newer 2020.2.5 b20827
2021.0 b21331

You may experience a workspace hang or "Error running translation". This occurs when FME is building bulk mode feature from regular features in the following options:

  • FeatureJoiner
  • AttributeKeeper (Create Bulk Features=Yes)

  • FFS Writer (Enforce Strict Schema=Yes)

  • SQLite Non-Spatial Writer

  • MapInfo Extended Writer

or input features have attributes with missing values for some chunks of bulk mode features and not others resulting in a crash if the schema changes.

Upgrade to FME 2021.1 build 21611 or newer 2021.1
FMEENGINE-70115 AttributeFilter version 4: When using attribute values with characters separated by a space, they are not filtered Upgrade the transformer to version 5 or upgrade to FME 2021.0.3.2 build 21332 or FME 2021.1.0.1 build 21614 or newer. 2021.0 b21302 2021.0.3.2 b21332 or 2021.1.0.1 b21614
FMEENGINE-70231 When using the VertexCreator in Add Point mode to create point features, the output features are lines instead of points.  This will most frequently occur with CSV and Excel input data sources. This is a conflict with intentional behaviour that automatically generates points when latitude/longitude attributes are detected.  Article: Known Issue: VertexCreator creates lines instead of points 2021.1 b21607 2021.2 b21771
FMEENGINE-70732 Geocoder: Unavailable to add a new Geocoder transformer from the Transformer Gallery or Quick Add. Existing workspaces will still run with the Geocoder, but it may be listed under "Upgradable Transformers" to upgrade to an FME package version. However, the updated Geocoder package is available in FME 2021.2 and is newer. Copy a Geocoder transformer from a previous build of FME 2021.1 or upgrade to FME 2021.1.3 build 21631 or newer. 2021.1.2 b21627 2021.1.3 b21631

Use the ID to select the layer
Open the feature service that you want to add in a web browser, in the web URL, there is an "id="
Copy the value to the "Feature Service" parameter for the ArcGIS Portal Reader inside brackets e.g.  (64d00a7c2ed14b0f9da3857d83bd40aa)
2021.2.4 b21813

For ArcGIS Portal, if the password contains special characters such as @,#,$,%,&,* or !.

The following error message encountered  "Check your credentials and try again. The error code from the server was '400' and the message was: 'Unable to generate token. Invalid username or password.'" is displayed. 

The issue is encountered with both Web-tier and Portal-tier authentication i.e. 

  • Generate Token 
  • Basic 
  • Digest
  • NTLM / Kerberos 
Use Web connection for ArcGIS Portal(Oauth) to connect to the portal instance. (Works for Generate Token or SAML Authentication only)   2020.2.0.0 b20787 2021.2.2
FMEDESKTOP-11986 Sorter fails with space in attribute name when passed as a parameter Simply use the attribute name in the Sorter.

DEVOPS-1721 The JDBC Connection String specified in a distributed/fault-tolerant install is ignored. In the fmeDatabaseConfig.txt the connection string is jdbc:postgresql://:5432/fmeserver. Edit the DB_JDBC_URL in the fmeDatabaseConfig.txt to point to your connection string and restart FME Server to apply the change.  2021.2+ 2022.0 b22294
FMESERVER-17724 Trying to edit an FME Server Web Connection in the Web UI there is an error "Some input parameters are malformed".

This error occurs if the FME Server Web Service definition was published to FME Server from FME Workbench 2021.2+. However, if the web service was uploaded by a restore you will not encounter this problem. To resolve the issue, delete the web service definition and publish it from an older version of FME Workbench and you should be able to make changes through the Web UI.

Alternatively, edit the Web Connections in FME Workbench and re-publish them. 

2021.2+ 2022.0 b22305

A server app (workspace or gallery) has ‘Require Authentication’ enabled and the allowed user is a user imported from Azure AD. When this user navigates to the app URL they are prompted to log in. After selecting ‘Sign in with Microsoft’ they are redirected to the FME Server home page instead of the app.

First, log into FME Server and then go to the server app URL. 2021.2+ 2022.1 b22600

FMESERVER-17998 In an Automation you configure a Schedule with a set End Time, then start the Automation. Once the End Time passes you cannot stop the Automation. The error is: 

Unable to disable '<AUTOMATIONNAME>': Schedule task (Category: <UUID> Name: <UUID>) must have an end time greater than the scheduler current time.
Duplicate the Automation (this will copy it in a disabled state where it can now be edited) and then delete the original Automation. To duplicate the Automation go to  'Manage Automations'. Check the box next to the problem Automation and then select Actions > Duplicate.  2021.2+ 2022.1 b22585

WARN     FMEServerQuartzScheduler_Worker-4   406411 : Job submission failed. Please ensure Transformation Manager is available. Category: <category> Name: <scheduleName>

ERROR    pool-2-thread-1 406439: An error occurred while triggering: QSInvalidRequest

Open each schedule where the ownership has been changed and resave them. 2021.0+ 2023.0 b23113
FMESERVER-16186 In an FME Server App, you cannot click OK to run the app. This is likely because the workspace app contains a parameter that is required but is not visible and has no default value. Either set a default value or make the parameter visible. 

In the fixed versions of FME Server, users will be prompted to select a value for the parameter.

FMESERVER-18922 If FME Server is hosted in a different time zone when creating a Basic or CRON Schedule (or Schedule in an Automation) the start and end times are adjusted. For example, if my current Server time: Fri-02-Sep-2022 11:30:00 AM -0700 and I set my schedule to start at 2022-09-02 20:00. After saving the Schedule it becomes 2022-09-02 13:00. Build a Schedule using the 'Repeat on Interval' Schedule Type.  2021.2.6 2022.2 b22729
FMESERVER-19159 In a Fault-Tolerant installation when the Core with the 'Active Job Router' fails, the remaining engines do not connect with the second Core Job Router. They will appear available in the Web UI but will not detect jobs in the queue for processing. This issue resolves itself after two hours.  In fmeEngineConfig.txt set the RECEIVE_TIMEOUT directive to 90000. Save the file and restart FME Server to apply the change. Setting this directive forces the Engine to terminate itself after it does not receive a translation request for the specified time, effectively breaking out of the hung state. 2021.2.5 Unresolved
FMEDESKTOP-13465 ArcGIS Online Web Connections created from new ArcGIS Online Web Services do not work on FME Server. When trying to add the URI to the web service after publishing to FME Server, an error "Some of all of the input parameters are invalid" is displayed on the UI. This is due to URLs needed for oauth 2.0 that are missing on FME Server. Upgrade to FME Server 2022.2.1 Upload AGOL webservice from FME Workbench 2020.  2021.2.6 2022.2.1
