Error parsing custom headers

Error

Error parsing OpenAI-Compatible headers: <value> is not a valid JSON.

Why this happens

The custom headers field in your OpenAI-Compatible provider settings contains invalid JSON.

Fix

1. Open Neural Inverse settings → OpenAI-Compatible provider
2. Find the custom headers field
3. Enter valid JSON:

Correct:

{"X-Custom-Header": "value", "Authorization": "Bearer sk-xxx"}

Wrong:

X-Custom-Header: value

{X-Custom-Header: "value"}

Common mistakes

• Missing quotes around keys: {key: "value"} → {"key": "value"}
• Trailing comma: {"key": "value",} → {"key": "value"}
• Single quotes: {'key': 'value'} → {"key": "value"}
• Putting the model name in the headers field instead of the model field

If you don't need custom headers

Leave the field empty — it's optional. Most providers only need the API key and endpoint.
