4Hi
Can anyone out there help with a problem I'm having creating a custom connector?
I'm using the connector to post to a team channel with an in line image, something there is currently no built connector for. I am basically copying the URL and JSON payload from the MS graph API documentation page, the 'send inline images along with messages' section of this page Send chatMessage in a channel or a chat - Microsoft Graph v1.0 | Microsoft Docs.
The URL I'm using here is https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}/messages
Having entered all of this in the Import from sample section of the definition page of new custom connector, I get the warning 'unable to resolve schema' on the body of the post.
I know the URL and payload are both valid as I can use them to post via the Graph API explorer, but when I try use the custom connector in a flow I get an error saying I need to fix expression for the input parameters.
The parameters I'm giving the connector match with the values that have worked in the graph explorer so I believe the problem is with the schema validation problem on the custom connector, but I've been able to find nothing to fix this.
Looking in the Swagger editor I do get 2 error messages about the URL parameters, but I believe this is a 'red herring' as I have another custom connector that works fine and that also shows the same error for each URL parameter.
Has anyone come across this problem and knows the solution?
