Deployment of Web Connection LinkedService fails using User Assigned Managed Identity with BadRequest #732
Description
While trying to deploy a DataFactory linked service of type "Web Connection" using a user assigned managed identity results in the following error. It looks like the credential is an object and not a string. The schema might be wrong or the encryption requirement may not match the schema. I get the same result in the portal as when doing an ARM template deployment.
