spaces before SSML tags cause internal server error for Azure TTS Instances

[JorySchossau]

Log File: log.txt

Describe the bug

Putting spaces before the prosody tag in SSML and using this python API causes an internal server error. However, Speech Studio processes this correctly.

this will error
   <prosody contour="(1%, +19%) (45%, -12%) (100%, -36%)">
   TITLE TEXT
   </prosody>

this is ok
<prosody contour="(1%, +19%) (45%, -12%) (100%, -36%)">
TITLE TEXT
</prosody>

To Reproduce

Here is the input SSML that causes the problem. Remove leading spaces from tags to fix the problem.
