Python from server error: AttributeError: type object 'Retry' has no attribute

[csh8428]

I have a workflow that is trying to write to Smartsheet. It works locally, but not from desktop designer on the server

Local PC proxy settings: Automatically detect: off, use setup script: on, manual proxy setup Off

Server proxy settings: Automatically detect: off, use setup script: Off, manual proxy setup: Has an our proxy address and port, and api.smartsheet.com is in the exception list

Error: Python (1): ---------------------------------------------------------------------------

@csh8428 may try to upgrade the package urllib3 and try again

pip install --upgrade urllib3

I found the solution here

It seems to be a problem with a deprecated method from urllib3 (used by requests):
https://stackoverflow.com/questions/65289720/attributeerror-retry-object-has-no-attribute-method-whitelist

In my environment, installing python-keycloak-0.25.0 also installs requests-2.25.1 and urllib3-1.26.5. This works fine, but I started having this problem after running pip install against a requirements.txt file that I have for test purposes that downgrades the requirements.txt version to 2.24.0.

I guess that a quick fix would be to force freezing the requests and urllib3 packages to the versions that are installed by default (that seem to work fine):

pip install requests==2.25.1 urllib3==1.26.5
