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!
