Calling Actions from Copilot Studio

Cannot add output for custom connector action

Posted on by 11



I have an action that uses a custom connector to call an external API for which I am unable to set the output:




This used to work fine when I last tested this action two months ago. The custom connector itself is confirmed working.


I have tried to recreate the action, but the add output button remains greyed out.

Any idea what I'm doing wrong?

    Will do, thanks! I am experiencing this issue in two different tenants. Again, previously this connector was all working and had an output defined.
