Error message

1 - Error loading MSP configuration for org %s

What it means

Wrapping error in NewApplicationOrgGroup: msp.GetVerifyingMspConfig failed for the organization named in %s. The MSPDir is missing, unreadable, or does not contain a valid MSP structure (cacerts etc.), so the org's crypto material cannot be embedded in the channel config.

Solutions

1. Verify the org's MSPDir path in configtx.yaml points to a valid MSP directory containing admincerts/cacerts
2. Regenerate crypto material with cryptogen or the correct CA tooling if it is missing
3. Check MSPType is 'bccsp' (the expected value for standard fabric deployments)
