Error with OpenAI node

[emil17]

I have an issue with workflow. Basically I am using webhook, open ai and respond to webhook nodes. When testing on Postman everything is good, but when using Flutterflows dashboard it throws:

Bad request - please check your parameters
Invalid value for ‘content’: expected a string, got null.

I am self hosting the n8n on render.

What can be an issue?

Generally, if one client works an another doesn’t, there is something different in how the two of them are sending the request. Double check that Flutterflows is including a body in the request, etc.

yeah, I configured that

{
“message”: “What’s capital city of Norway?”
}

It will help if you edit your initial post and add your entire workflow in a code block and include screenshots of where you are seeing the error message.

To post the workflow.

1. Select all nodes in the n8n editor
2. copy (ctrl/cmd-c)
3. Add two separate lines with 3 back-tics and paste (ctrl/cmd-v) the workflow nodes from the clipboard.

The code block should look like the following in the forum editor, and the preview should render the workflow similar to how the actual n8n editor does.

```
{
   "nodes":  [
     ...other json...
   ]
}
```
