Error fetching options from LinkedIn

I am using this workflow template and I am receiving the error in the image below. I’ve also tried making a developer app following this video, but I’m having similar issues.

Which credential type are you using? If you are posting as a user you will need to disable the organisation support option in the credential.

What should I do if I am posting as a user and also as an organization?

I have tried creating two credentials, one for organization and the other for personal user, but once I set up one, it seem to deactivate the other in the workflows where they are active…

Did you find the solution please ? I have the same problem.
