@andrzejwp Please find below warnings we noticed in the swagger validation log which are worth to consider.

ValuePath: /definitions/CTD/x-ms-dynamic-schema/value-path The dynamic operation expects a property on the specified path 'schemaDefinition/allOf/1' which should be defined in the successful response of the invoked operation 'GetContentTypeSchema'.

@sriyen-msft thanks for the comments and suggestions. I addressed them in the recent commit. Regarding the warnings - they are, unfortunately, impossible to fix at this point because:

1. Power platform does not support OpenAPI composition (allOf keyword)
2. Flotiq uses composition in the Content Type schema definition

so we will have to live with this until either of these gets resolved ;)
We have tested this, and despite these warnings, the integration works as expected.

Resolved
