+19Reading Living Atlas layers anonymously (no authentication) is done using the Standalone Server source type but the 3.21.2 package errors. This is a publicly shared service you can try:
https://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/USA_Major_Cities_/FeatureServer
Safe are aware of the issue, you can revert to 3.20.2 to avoid the issue.
+6I am also getting an error when connecting to publicly available feature services (not Living Atlas) using the Standalone Feature Service option with the Esri ArcGIS Feature Service Reader format after upgrading the Esri ArcGIS Connector package to 3.21.2. After removing the package and installing the previous version as recommended above, the error was resolved.
Adding this comment to the thread just to note that the issue is not limited to Living Atlas layers. It seems any anonymous connections will fail with the latest version.
The specific error I receive is:
“ERROR |Message Type: fme::internal::_v0::py::Exception
ERROR |Python Exception <AttributeError>: 'NoneType' object has no attribute 'conn'”
+5Hey, I’m affected by something similar.
FME Form: 2025.1.3
ArcGIS Connector: 3.20.2
The ArcGIS Connector package version above functions for standard ArcGIS Feature Service readers.
However, Feature Readers set to read a Standalone Server with a Basic Auth connection (Esri ArcGIS Login: safe.esri-agol) fail with errors like:
Python Exception <AttributeError>: 'HTTPBasicAuth' object has no attribute 'conn'
When upgrading the ArcGIS Connector package, even the standard ArcGIS Feature Service readers fail with the same error. I’ve tried the following versions: 3.22.0, 3.21.3, 3.21.2.
