Error 500 returned when requesting EC certificate with Firefly

PROBLEM SUMMARY Unable to get an ECC certificate from Firefly using vcert v5.1-rc1

STEPS TO REPRODUCE Have a working Firefly, valid JWT, and Rest endpoint working, use

vcert enroll --platform firefly --token $JWT_THIS --url https://10.11.11.1:8003 \
--verbose --cn vcert01.demo.example --no-prompt --csr service -z 'Demo Policy 1'  \
--trust-bundle ./myff.pem \
--key-type ecdsa

EXPECTED RESULTS

I'd expect a PEM file to be returned.

ACTUAL RESULTS

This is the error returned (Error 500)

COMMENTS/WORKAROUNDS

Changing the key type to RSA => no errors

vcert enroll --platform firefly --token $JWT_THIS --url https://10.11.11.1:8003 \
--verbose --cn vcert01.demo.example --no-prompt --csr service -z 'Demo Policy 1' \
--trust-bundle ./myff.pem \
--key-type rsa

returns the certificate as expected
