initializing configtx manager failed

Error message

initializing configtx manager failed

What it means

Wrapped failure of configtx.NewValidatorImpl while constructing the config-update validator: the config tree could not be mapped or the channel ID/policy setup failed, so the bundle cannot validate future config updates.

Solutions

1. Inspect the wrapped error (nil config, bad channel ID, mapping failure)
2. Fix the underlying config structure and rebuild the bundle
