Unexpected Error during Web API HTTP Request: Server Protocol Violation

chrispotvin — Mon, 08 Jan 2024 14:18:10 GMT

Good morning BP Community,

I am receiving a Blue Prism internal error that details a Server Protocol Violation when triggering a POST method to an external API (Webservice). I have confirmed that the same call works in Postman and with curl on the VM. The POST does not use any authentication and is an HTTP endpoint.

Has anyone has received this error before? I could use some help in debugging what this could be.

Thanks!

Hi Christopher,

Are you using the Blue Prism Web API Service feature, the Utility - HTTP VBO, or something else to call that external service?

Cheers,

Eric

Hi Eric,

I'm having the same issue and using Utility-HTTP.

@Prashant Mittal,

Are you using the latest release of the Utility - HTTP VBO available from the DX?

Cheers,

Eric
