APIM API Timing Out with a SMAPI 422 Response

Question

I am seeing this 422 message in APIM. I think it is to do with the size of the mocked response i.e. 2.8 Mb. The actually mocking is working perfectly from outside of APIM, however, when I try and update the API or even try to delete it I see this 422 exception in APIM.

Also, the endpoint does not even load in APIM, it times out with a "Could not load details for operation...".

My question is, what are the limits here, mocking responses? I only see a 64 Kb limit on a validation schema policy within APIM.

Hi @Anonymous Thanks for reaching out. There are operations in the API that have a really large schema associated with them. That causes the retrieve operation to time out. The only workaround is to delete those operations and maybe re-create them with a smaller sample text or you should upgrade from developer sku to standard/premium sku.

please try deleting the operations using direct MAPI REST call using a SAS token.

For example:

DELETE https://{servicename}.management.azure-api.net:3443/subscriptions/Sub ID/resourceGroups/ResourceGroup Name/providers/Microsoft.ApiManagement/service/APIM service name/apis/Api Name/operations/operation name?api-version=2021-01-01-preview

Content Type: application/json
Authorization: SharedAccessSignature <REMOVED>

let me know incase of further queries, I would be happy to assist you.
