Log forwarding from functions to logtail/Better Stack throws 401

Asked by robert

I set up a function with the following project.yml file

packages:
  - name: sample
    actions:
      - name: hello
        runtime: 'python:default'
environment:
  LOG_DESTINATIONS: '[{"logtail":{"token":"MY_SOURCE_TOKEN"}}]'

When executing the function I get the following error

2025-04-26T11:43:54.97811523Z  stderr: Failed to flush logs: failed to ingest log line, code: 401

A curl using the token works tho

curl -X POST "https://s1287463.eu-nbg-2.betterstackdata.com" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer MY_SOURCE_TOKEN" \
-d '{"message":"Test from curl"}'

Does anybody have an idea how I could investigate the issue?

The support was super helpful and we solved it. Choose “Digital Ocean” as Platform on logtail/Better Stack instead of “HTTP”. Documentation still says “HTTP”. So that’s what confused me.

Hi there,

I could suggest double-checking the MY_SOURCE_TOKEN value to make sure that it is correct and that it does not have any whitespaces for example.

If everything looks right and it’s still failing, it’s worth reaching out to the DigitalOcean Support to double-check if there’s an issue on their side.
