I was trying to make a simple workflow with chatgpt open ai and connected simple chat trigger with generate image gpt but it was sending bad parameter error then
I was trying to do it with http request still the same message.
What should i do there is no solyution available in the web as well i searched everything.

This is the error:
Bad request - please check your parameters

Hi, Works fine for me

You are providing an actual prompt right? since yours was empty

Also, this is just for performing a manual test, for a chat setup you need to do differently

For the chat it’s like this, but you need to add more logic to store it somewhere or your another trigger like telegram / whatsapp to return the image directly to the chat.

I pasted your code in my workflow and got the same error?

Is there something messing with the api?

Can you please provide the flow of how you made it with getting the api as well.

It will be very helpful.

Hi,

not sure, i’m not doing anything special TBH.

I know my API key works in general and I just put the nodes on there with basic paramaters. I just changed the prompt expression.

Did you fund your account ? does it have credits? Did you set any other limitations?

reg,
J.

i am using free trial of n8n
and for api i used both free and parid version of gpt’s api

Can anyone confirm this. Do we need to buy open ai api to use the image generation in n8n?
