Getting 417 response when using Expect header

Questions
1

Hi everyone,

I noticed that whenever the Expect header is present in a request, n8n immediately responds with a 417 Expectation Failed error.

Has anyone else run into this issue?

  • Is it expected behavior in n8n?

  • Is there a way to configure n8n to ignore or handle the Expect header instead of failing right away?

I did some more testing, and it looks like the issue only happens when the Expect header has an empty value. If I set it to 100-continue, everything works fine and n8n no longer returns 417.
