failed obtaining orderer config from bundle

Error message

failed obtaining orderer config from bundle

What it means

After building the bundle, EndpointconfigFromConfigBlock calls bundle.OrdererConfig(). This returns ok=false when the channel configuration does not contain a valid Orderer config group, so the function cannot enumerate orderer organizations and their TLS CA certs.

Solutions

1. Verify the block passed is actually a config block (type_header type CONFIG) for the correct channel.
2. Regenerate the genesis/channel config ensuring the Orderer section with orderer organizations is present in configtx.yaml.
3. Check that the channel was created with a profile that includes Orderer: -> Organizations entries.
4. Ensure the orderer is joining the intended channel and not one configured by another network.

// Confirm block is a config block of the expected channel before use
if !protoutil.IsConfigBlock(block) {
    return errors.New("block is not a config block")
}

func isConfigBlock(b *common.Block) bool {
    return b != nil && b.Header != nil && protoutil.IsConfigBlock(b)
}

When it happens

Trigger: Passing a config block from a channel whose config has no Orderer group (e.g. an application channel block missing the Orderer section, or a non-config block mistakenly passed in), so bundle.OrdererConfig() returns false.

Common situations: Pointing an orderer's cluster/block-puller at the genesis block of the wrong channel type, channel created without orderer orgs, or passing a regular (non-config) block where a config block was expected.
