[BUG] "Failed to read request" PATCH method for endpoint /submodels/{submodelIdentifier}/$value

[LinhPhan210]

Hi all,

Describe the bug It seems that the PATCH method for the endpoint "/submodels/{submodelIdentifier}/$value" is not working at the moment. I have tried using various submodels, copied the response body from the GET request to the request body of the PATCH request, but I always receive a 400 error.

To Reproduce On Postman or similar app

1. make a GET request to any submodels: "/submodels/{submodelIdentifier}/$value"
2. copy the response of it
3. paste to the request of PATCH method: "/submodels/{submodelIdentifier}/$value"
4. make the request
5. See error

Expected behavior It should return status 204

Error { "type": "about:blank", "title": "Bad Request", "status": 400, "detail": "Failed to read request", "instance": "/submodels/aHR0cHM6Ly9tdXJyZWxla3Ryb25pay5jb20vaWRzL05ldHdvcmtDb25maWd1cmF0aW9uLzIyMTJfOTA3Ml85MDMyXzQ3NDQ=/$value" }

Hi @aaronzi,

i have read the API Spec here:

• GET request: https://app.swaggerhub.com/apis/Plattform_i40/AssetAdministrationShellServiceSpecification/V3.0_SSP-001#/Asset%20Administration%20Shell%20API/GetSubmodel-ValueOnly
• PATCH request: https://app.swaggerhub.com/apis/Plattform_i40/AssetAdministrationShellServiceSpecification/V3.0_SSP-001#/Asset%20Administration%20Shell%20API/PatchSubmodel-ValueOnly

As in the specification, the schema of response body from GET request same as the schema of request body from PATCH. Isn't that mean, that it should work when use the response of GET as request body for PATCH? but it returns error
