could not create consortiums group

Error message

could not create consortiums group

What it means

Wrapping error in NewChannelGroup: NewConsortiumsGroup failed while building the Consortiums section (used for orderer-generated channels). Usually a bad consortium member organization or MSP configuration; the wrapped error names the member that failed.

Solutions

1. Fix the consortium member organizations listed in the profile's Consortiums section per the wrapped error
2. Ensure each member org's MSPDir and ID are valid and that orgs are not marked SkipAsForeign incorrectly
3. Remove the Consortiums section if consortiums are not needed for the generated config
