Hi,
I have a Zap that posts to my self-hosted Mattermost 10.2.1 server. The Zap currently throws an error, likely due to a downrev version of the Mattermost integration in Zapier (1.9.0) however, when I attempt to upgrade the Mattermost integration in my Zap, any credentials I select immediately transition to “Expired” and Zapier requests I reconnect them. The “reconnection” does not visibly fail, but after reconnection, the accounts are immediately marked as expired. I have recreated the OAuth app in Mattermost, I know nothing is expired from my side, the oauth workflow succeeds, but I can’t seem to get a working Mattermost integration again. What am I missing? Is the integration simply broken with current versions of Mattermost?
