Getting Error "Expected input credential was not present"

I'm trying to reach https://sandbox.api.visa.com/vcpe/v2/pan/enrollment but I'm getting a 400 error with the message "Expected input credential was not present". I'm able to reach the helloworld endpoint so my certs should be correct. I'm also using MLE for my payload.

 

Here is the response:

If anyone could please let me know which input credential I'm missing, I'd greatly appreciate it!

Re: Getting Error "Expected input credential was not present"

I was using the wrong format for keyid in my header, I used "keyid" instead of "key_id" and it fixed my 400 error. However, I am now getting an internal error:

.Can anyone help with why I am getting this error? I don't see the code on the error codes page.

Also for reference, this is my request header:
