ChatGPT 5 400 'modalities' Error

Hello!
I’m getting this [400] Unknown parameter: ‘modalities’ error.

Not using the raw API request module. Am I doing something wrong?

Make.com needs to manually add some parameters to add support for GPT-5. Should be coming soon

Hi, see my response in this similar thread and feel free to use the “Create a model response” module instead.
