could not get MSPs

Error message

could not get MSPs

What it means

Returned by validateCollectionConfigMemberOrgsPolicy when the mspMgr cannot supply MSPs while compiling the collection's member-org policy. The policy envelope was structurally present but the MSP context needed to validate it is unavailable at validation time.

Solutions

1. Check the wrapped error and the channel's MSP configuration
2. Retry after the channel config/MSP setup is healthy
