I add a Perplexity tool node, I click on credential to connect with, create new credential, I paste my Perplexity API key, I get the following error: Couldn’t connect with these settings.
I have tried several times, I have also created different keys, but I keep getting the same error message. APIs from other websites are working perfectly fine. Can you please help me with this?

This is a known issue, which will go away in 1.112.0, for not you can just ignore the error in the credentials and start using it.

## Describe the problem/error/question

No workflow example needed.
## Share the output returned by the last node
While credentials page fails to verify, if ignored, the node itself works with appropriate models.

Thanks, but it doesn’t work. My API definitely works, but for some reason the Perplexity node isn’t…
