Edit: If i use "-- None --" or "[Custom Vault Name]", i'm getting "credential validated", wut?!
Hi there,
After i followed these steps to activate and setup external credential vault (in first instance, based on a local host file), i made some minor change on .java file, and compile to .class.
However, when i test credential (xpto_user2) seems to be fine, but in wrapper.log appears me that:
2023/12/09 11:14:44 | Error while resolving credential id/type[xpto_user2/windows]
This is my actual .java file:

}
Then, i create a .class from from that java and put it on "C:\ServiceNow\API\Java\com\snc\discovery" named "CredentialResolver.class". Then, i create .jar and put as mid server jar on ServiceNow instance (Utah Patch 7b).
1) How can is possible to retrieve me that error, when i dont have any of this sentence on my code?
2) How can is possible, in my second host where i have mid server installed getting these error?
