Dears,
Via a flow, I created a process to extract zip file directly from the Sharpoint interface via a sharepoint trigger.
Unfortunately, if the zip is to heavy, the extraction is aborted.
In that case, I would like to send a message via Teams to the user.
In "Post a message in a chat or channe" I use the username field of SharePoint trigger.
But when running the flow, there is a message error.
Does anyone have an idea why ?
I tried also to go through a "get profle 365" but the problem move to this step.

The error message

Thank you in advance for your help
