failed obtaining MSPs from MSPManager

Error message

failed obtaining MSPs from MSPManager

What it means

EndpointconfigFromConfigBlock parses a config block into a channelconfig.Bundle and then asks the bundle's MSPManager for its MSP instances. This error is a wrap of whatever failure occurred inside MSPManager.GetMSPs(), meaning the channel MSP configuration (the MSPs defined in the channel config) could not be instantiated, e.g. invalid MSP definition material.

Solutions

1. Inspect the wrapped cause in the error chain; it names the MSP and the exact material problem.
2. Regenerate the channel config tx with valid, unmodified MSP crypto material (configtxgen with correct crypto-config).
3. Verify the MSP definition in the config block (decode with configtxlator) and fix root/intermediate certs, admin certs, or FabricNodeOUs settings.
4. Re-issue the config update through a proper config update transaction, not manual block editing.

Example fix

// before: hand-edited MSP certs inside config block
// after: regenerate config tx
// configtxgen -profile MyChannel -outputCreateChannelTx mychannel.tx -channelID mychannel
// then submit the update via the ordering service

// Verify MSP material is parseable before building endpoint config
rootCAs, err := caCertPool(certs)
if err != nil { return fmt.Errorf("invalid CA certs for MSP %s: %w", mspID, err) }

cfg, err := cluster.EndpointconfigFromConfigBlock(block, bccsp)
if err != nil {
    if strings.Contains(err.Error(), "failed obtaining MSPs") {
        var unwrapped error = errors.Unwrap(err)
        log.Errorf("MSP manager failure: %v", unwrapped)
        return fmt.Errorf("config block MSP material invalid: %w", err)
    }
    return err
}

When it happens

Trigger: Calling cluster.EndpointconfigFromConfigBlock (directly or via BlockPuller / EndpointconfigFromSupport) with a config block whose Application/MSP config contains malformed MSP definitions (bad intermediate certs, wrong node-OU config, invalid crypto material) so bundle.MSPManager().GetMSPs() returns an error.

Common situations: Channel config transactions generated with corrupted or hand-edited MSP certificates, MSPs with unsupported type or missing admin/root certs, or config blocks copied between networks with inconsistent MSP material.
