PROBLEM SUMMARY
Unable to use vcert getcred to generate new token.
My new p12 file was generated using java keytool and i guess vcert does not know how to handle it based on the error i get.
My old p12 file was generated on Windows.
I can use CURL to request a token using the same p12 file so my file is not the problem.

STEPS TO REPRODUCE
How i generated my p12 file.

keytool -genkey \
-alias cba_cert \
-validity 180 \
-keyalg RSA \
-keysize 2048 \
-keystore certfile.pfx \
-dname "REDACTED"

I then had the certificate signed by our CLM instance and imported it back into the file.

./vcert getcred -u https://clm-api.com --p12-file certfile.pfx --p12-password secret --client-id MyID --scope "certificate:manage" --format json

EXPECTED RESULTS

ACTUAL RESULTS

COMMENTS/WORKAROUNDS
Generate a token using the same p12 file but with CURL works.
