Hi,

if I understand you correctly, you sign the CSR with a self-signed
certificate that does not use the same key as the CSR? This is not
supported by the default workflow - you can use the "signer on behalf"
feature which requires to use a known certificate, otherwise you need to
change the workflow.

See
