When i use another funcion in the same node, like “Analyse Image” it is working, but if i change to “Generate Image” it is going to wrong

No answer for it? I have the same problem apparently the OpenAI image Node is waiting for a parameter Text from previous node. But this node doesn’t have that option and that made half of my workflows die. I upgraded N8N 4 versions in a row so I can precisely tell where it broke but for sure is broken in the last version.

I restored my container from an Image backup I made before upgrading and everything works great on it. So I’m back to 1.64.3 with no problem

I solved it by replacing the generate image block with a direct http request for openAI to generate the image.

curl https://api.openai.com/v1/images/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -d '{
    "model": "dall-e-3",
    "prompt": "a white siamese cat",
    "n": 1,
    "size": "1024x1024"
  }'```

Same problem here, I don’t want to change to Manual API call, because I would have to do this in several nodes and modify several things in each workflow.

Same problem with me, I updated my docker image to 1.69.2 this morning. I’ve reverted back to the previous image.
I love n8n, but this issue is definitely made me a little wary.

fixed in 1.70.0

Same problem here. I use 1.69.2
