Expect: 100-continue over on-premises data gateway

(0) ShareShare
ReportReport
Posted on by

Hi,


I have an issue with one of my custom connectors that calls PUT request over the on-premises data gateway and transfers a file (form-data). When I run the custom connector over the on-premise gateway, the gateway adds additional header "Expect: 100-continue" which breaks the connection. When I run it (same connector) over the internet directly to the server the "Expect" is NOT present and request is completed successfully.

Is there a way to prevent on-premises data gateway from adding "Expect:" header.
