Qlik Sense for Windows: ODAG API error 500 when Expect: 100-continue header is used

[Damien_V]

The Qlik Sense ODAG API is returning error 500 when the Expect: 100-continue header is used

Environments:

Qlik Sense Enterprise on Windows  June 2019 and later

Resolution

Some clients, such as the .NET framework and cURL send the Expect:100-continue by default.

The Qlik Sense ODAG API does not support this header and the API call will fail with an error 500 Internal server error when this header is used.

The header should be removed from the request for it to work.
