Sending header with a … char throws invalid char

[nervetattoo]

Using auth0 generated tokens and trying to send them as a bearer token failed. I narrowed it down to the … character causing the issue.
Easily replicated:

config:
  target: https://google.com/
  phases:
    - duration: 1
      arrivalRate: 1
  variables:
    token: …
scenarios:
  - name: Fail
    flow:
      - log: "{{ token }}"
      - get:
          url: "/"
          headers:
            authorization: "{{ token }}"

Removing the header and everything works again. Logging the token works.

hi @nervetattoo 👋 can you double-check the values you're getting back from Auth0?

The "…" character in your example is the U+2026 ellipsis character. HTTP header values aren't supposed to have any characters outside of ISO-8859-1 set. It's not ellipsis-specific, e.g. replacing the ellipsis in your script with the Cyrillic character "ж" results in the same error. Node.js rejects anything outside of that character as a security measure.

Feel like I might have been tricked by devtools UI truncating. But I did extract values even with "copy as curl". Generated new tokens that did not contain ellipsis. I'll rather revisit if I get tokens with ellipsis again, dig deeper then.
