Le Azure Core is broken when trying to send requests with content-type: text/plain. #12137
Description
- Package Name: azure-core
Describe the bug
We disregard the content-type header and try to set the body as json unless it is an xml element tree. See https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/core/azure-core/azure/core/pipeline/transport/_base.py#L705
We either have to provide a new parameter type (e.g. body in addition to content, or we should honor the content-type header when we serialize the information.
