Hello n8n Team,
I am experiencing a bug with the ElevenLabs node on the n8n Cloud platform.
The Problem:
The “Convert text to speech” operation fails with a 401 Authorization failed error.
Contradictory Evidence:
- The credential test in the “Edit ElevenLabs account” window shows “Connection tested successfully”.
- I have confirmed my API key is valid by making a direct API call using cURL, which worked perfectly and generated an audio file.
Troubleshooting Steps Taken:
- I am on the latest n8n Cloud version.
- I have confirmed my ElevenLabs account has plenty of character quota remaining.
- I have tested with both custom voices and standard voices (e.g., “Rachel”).
- I have tested with both dynamic and simple hardcoded text (e.g., “Hello world”).
- I have regenerated my API key multiple times.
The error persists despite all of these steps. Since the curl test works, the bug appears to be within the n8n node’s execution logic.
Could you please investigate this issue?
Thank you!
