Python KeyError exception when authenticating login for ArcGIS Portal Feature Service Reader/Writer
Hello. I am trying to use the Esri ArcGIS Portal Feature Service Reader/Writer in FME Desktop 2018.1 and am getting a Python KeyError exception when trying to authenticate the login. I am using "Generate Token" as the authentication type, and trying to connect to an instance of Portal for ArcGIS (10.6.1).
Here's the relevant excerpt from the log:
|INFORM|ArcGIS Portal Feature Service Writer: Logging into '[host url]' as user '[username]' |ERROR |Python Exception <KeyError>: u'token' |ERROR |A fatal error has occurred. Check the logfile above for details |ERROR |... Last line repeated 2 times ...
The strange thing is that this workspace ran successfully a few days ago.
Any input would be appreciated. Thanks!
Hi @neuwerld, are you still having this issue? If you are, can you share the full log with us so we can help look into it? It's strange that it stopped working. Did anything on the ArcGIS portal instance change?
Hi @neuwerld,
Are you able to login with your credentials using a web browser just fine? The error suggests that perhaps no token was returned during the authentication process.
Best,
Nathan

@XiaomengAtSafe @NathanAtSafe Thank you for the comments. I am still having the issue, but Nathan's comment gave me the idea to try to log in using a web browser. I found that I cannot log in to the particular host URL I used. I used the format https://server.domain.com:7443/arcgis, because that was the only URL that didn't return the "does not appear to be an ArcGIS Portal Instance" error. I can log in to https://server.domain.com/portal (and that seems like it should be the host used in the Portal Feature Service reader/writer) but I get that "does not appear to be an ArcGIS Portal Instance" error when using that URL. I'm not sure how the workspace worked a few times previously, but based on the fact that I can't login at the URL I was using I think that was probably the source of the error. I still don't know why none of the URLs I've tried are recognized as valid Portal Instances, but I have come up with a workaround anyway. I am now using a PythonCaller and ArcPy.
