    Turns out I missed a step in adding the AS3 module to my BIG-IP VE poc VM.

Hi Patrick,

I've helped a bunch of customers set up CIS and I've come across this log message a few times:

 

2021/10/04 21:21:43 [ERROR] [AS3] Response body unmarshal failed: invalid character '<' looking for beginning of value

 

Every time, it's been a problem with the CIS pod authenticating to BIG-IP. Can we double-check your credentials that are stored as a secret in K8s?

 

Also, if you created the secret with a yaml file, did you remember to base64 encode it? Here's an example of a secret that has the password of "DefaultPass12345!" base64-encoded.
