Hi Kris,
Thanks for your response, and apologies for my late one!
To answer your questions, yes, I did create a custom form for my SP list using PowerApps, and I did make sure to use my work O365 account, which is also a GA. Permissions are definitely not an issue.
What information are you asking for, regarding the InfoAbout bit? Where can I find that?
Also, to update, I also created an AzureAD connection, since our organization uses that, and I am experiencing the exact same invocation error when trying to do a similar lookup using AzureAD commands.
I created the O365 and AzureAD connectors after creating the form. I thought maybe I needed to recreate the form to take advantage of those connections, but even doing that did not resolve my issue. Any thoughts on what's going on here?
Thanks again!
