FME ENGINE-83531 ArcGIS Pro 3.3 ships with urllib3 v2.1 which has deprecated the retry options method_whitelist. DEFAULT_REDIRECT_HEADERS_BLACKLIST FME bundles and uses urllib3 v1.26.18, so this error does not appear.

Additional Information

Workaround

As a workaround for the error, place the following script in the startup Python script parameter:

import sys

sys.path.insert(0,r"C:\Program Files\ArcGIS\Data Interoperability for ArcGIS Pro\Python")

import urllib3

This Python script is meant to allow FME to use the older, shipped version of urllib3 instead of ArcGIS Pro's, which prevents the error from occurring. Based on testing, this workaround only works for a FeatureReader for the affected formats and not a regular reader.

 So the steps are:

1.  Add the Python script above to the Navigator pane's Tool Parameters > Scripting > Startup Python Script parameter.

2.  Add a Creator and FeatureReader.

3.  Add a connection between the Creator output port and the FeatureReader's Initiator port.

4.  Open FeatureReader and select the format, feature type, and so forth.
