Hello Modou Diouf - Thanks for reaching out to us.
It is possible that the HTTP request headers are not being captured by Azure diagnostics settings. Please see below to see if you can troubleshoot the issue.
- Check if the HTTP request headers are being sent with the request. You can use a tool like Fiddler or Postman to check if the headers are being sent with the request and if HTTP request headers are being captured by Azure using Azure Diagnostic logs feature.
- If the headers are not being captured by Azure, then you can try using Application Insights to capture the headers.
Hope this helps. and please feel free to reach out if you have any further questions.
