"AclCheckFailed" error while trying to open MS Teams chat through the button in a ticket for Microsoft Teams spokeIssue You are using Microsoft Teams spoke. When you try to open a Microsoft teams chat through the button in the tickets "Start Microsoft Teams chat", you are faced with this error.Error like: You checked the ACL and nothing has been modified. CauseUpon reviewing this with a few of our customers, we found from the transactions that the inbound API call "/api/sn_tcm_collab_hook/integration/createAndGetChatLink" threw a 403 response code.ResolutionAs you are using Microsoft Teams spoke, presumably, you configured OAuth with it & this error is being thrown while a user is trying to initiate a chat.This has been reported to us earlier by a few of our customers as well.This is due to OAuth Authorization failure (as we reviewed from the 403 responses in the transactions).This might have been addressed by the EndPoint team fixing it at the OAuth level. Hence, you are recommended to review this with the endpoint team.
