I have problems testing the project. I cannot verify the certificate that the cert-issuer created correctly. I have used cert-tools to generate the certificate, I have even modified the issuer\_id in the configuration file. But it keeps giving me the same “errors.invalidBlockcerts”. Looking at the code, it seems that the issuer’s certificate key is not embedded and I don’t know if it needs to be specified in some specific format. I have switched between branches of the different tools but I can’t figure out where the fault is. Could you tell me what configuration I have to have as well as the branches that are functional in production? Thank you
