error adding policies to channel group

Error message

error adding policies to channel group

What it means

Wrapping error in NewChannelGroup: AddPolicies failed while installing the channel-level (Applications/Orderer root group) policies. The wrapped error (e.g. invalid policy rule or unknown policy type) is the real cause; this wrapper just contextualizes it to the channel group.

// NewChannelGroup defines the root of the channel configuration.  It defines basic operating principles like the hashing
// algorithm used for the blocks, as well as the location of the ordering service.  It will recursively call into the
// NewOrdererGroup, NewConsortiumsGroup, and NewApplicationGroup depending on whether these sub-elements are set in the
// configuration.  All mod_policy values are set to "Admins" for this group, with the exception of the OrdererAddresses
// value which is set to "/Channel/Orderer/Admins".

Solutions

1. Inspect the wrapped cause: fix the offending policy rule or type in the profile's Policies section
2. Ensure required policies (Readers, Writers, Admins) are defined and use valid ImplicitMeta or Signature syntax
3. Regenerate with configtxgen once the Policies block in configtx.yaml is corrected
