Describe the issue/error/question

We try to send a message to Mattermost Starter Version Mattermost-Version: 7.0.1

We have setup a bot account with system-admin permissions and added these to the Test Channel.
We are using Teams in mattermost so we joined the bot account to Team A and into the channel.

The bot account is setup in credentials and test button is working.

What is the error message (if any)?

If we try to search the channel it will not shown in the list, also if we set the channel id via expression it will not work… But some other channels will be shown in the list if you leave it blank.

Hey @philippkayser,

I have just taken a quick look and it appears to be working, Out of interest does your Base URL end with a /, I found I had to remove it form my test to get it to work which is something we should fix at some point.

With the channel list not loading how many channels do you have in your instance? I did also test with Cloud which I think is probably 7.4 so a fair bit newer but we have not updated the node for a while so the Mattermost version shouldn’t matter.
