LinkedIn Module not showing URL preview or accepting ChatGPT generated image url

I’ve been trying to get this working for the last two days and don’t understand where the problem is…
I have two options. 1. Generate a link from ChatGPT and use the webhook to send the json details with the link URL to LinkedIn module. But that didn’t work.
2. I have created a ChatGPT image generation module and send the URL to LinkedIn module to only return the error:

" Validation failed for 1 parameter(s).

I tried to find the type “link” but only “article” is available. If I put the data simply in it, it doesn’t work.

I’m new to this but avid to learn. It’s my first scenario and just want to understand the things I miss.

Thanks for the help
