Hello

I've coded a simple Custom Connector on MSGraph API that calls via a GET an URL of this kind :

https://graph.microsoft.com/v1.0/sites/<mytenant>.sharepoint.com,<my_site_id>/drives

When I test in from Custom Connectors Wizard it's ok, Status 200, with a response.

I've made a Flow with this CustomConnector, but when I launch it PowerAutomate (Test Manually) fails with this error message :

ResponseSwaggerSchemaValidationFailure. The API 'graph-20api-5f3e2d0f3a25b04a35-5fe36bd7501b87b5c9' returned an invalid response for workflow operation 'GetBiblio2EnDur' of type 'OpenApiConnection'. Error details: 'The API operation 'GetBiblio2EnDur' requires the property 'body' to be of type 'String' but is of type 'Object'.'

Can someone help me please ? Thanks in advance !

(excuse for my poor English cos I'm french)
