Hyperledger Fabric - Block Inspecting Error

I want to receive a correct block extract containing transaction for a typical invoke transaction (non config transaction).

docker exec peer0.org1.example.com peer channel fetch 4 -c mychannel
docker cp peer0.org1.example.com:/opt/gopath/src/github.com/hyperledger/fabric/peer/mychannel_4.block .
configtxgen -inspectBlock mychannel_4.block > mychannel4.json

This makes it possible to receive a full pb2json decode for the fabric-samples like "first-network". But it doesn't work for the "fabcar" sample. Normally this should work too, right?

Any Ideas why and how to fix it?

../../bin/configtxgen -inspectBlock mychannel_3.block block3.json

You can make use of configtxlator tool to decode the block as a whole.

configtxlator proto_decode --type=common.Block --input=<your_block.pb> --output=<your_block.json>
