@Piyushmethi09 Did you find a fix for this issue? I have the same.

I hit this error recently and the problem - for me at least - seemed to be Docker volumes hanging around from a previous time the Fabric network was created. This was resolved by running:

1. ./network.sh down
2. docker system prune --volumes

I have the same error as you, but only while trying to add a second peer to the channel :

I don't understand why it attempts to recreate a channel, when I only want to add another peer to it.

If someone has a clue...
