But, when I try to create the genesis file with the command.

configtxgen -profile SampleAppChannelEtcdRaft -outputBlock genesis_block.pb -channelID channel1

I am getting below error

I can't comment since the reputation is low so now..., I got the same error,so I just check the "crypto-config" folder and found out that I don't have enough certificates

so I checked the "docker-compose.yaml" file and another file (I have a custom structure in my folders) that is responisible in creating certificates.And there I found out I made a wrong entering of PORT number for one of the organizations which is not matching with the PORT number of the organization mentioned in "docker-compose.yaml".

So, I corrected it, made the file run again, got the created enough certificates,now its fine.

this worked for me, let me know if you already got any other solution

The problem can be solved by regenerating users and peers crypto credentials

exp if using crytpogen :

cryptogen generate --config=org3-crypto.yaml --output="../organizations"

in case of CA (test-network) just run ./network down
