Error Upgrading Fabric component [orderer.common.server] Main -> ERRO 001 - hyperledger-fabric

Question

I'm practicing upgrading network components (orderer and peers) following the official hyperledger fabric docs. In particular I'm following this link to upgrade the orderer. I'm able to follow all steps, but I get an error at the last step when bringing up the orderer:
/test-network docker logs b0d56da4a9f082bc7c5c0dea1e81ba3bf30c55be8f306b0a27986c706a056da4
2022-10-24 14:53:07.899 UTC [orderer.common.server] Main -> ERRO 001 failed to parse config: Error unmarshaling config into struct: 2 error(s) decoding:
* cannot parse 'General.ListenPort' as uint: strconv.ParseUint: parsing "'7050'": invalid syntax
* cannot parse 'General.TLS.Enabled' as bool: strconv.ParseBool: parsing "'true'": invalid syntax
These are the commands I'm executing in order:
#1. Stop the ordering node.
docker stop $ORDERER_CONTAINER
#2. Back up the ordering node’s ledger and MSP.
docker cp $ORDERER_CONTAINER:/var/hyperledger/production/orderer/ ./backup/orderer/$ORDERER_CONTAINER
docker cp $ORDERER_CONTAINER:/etc/hyperledger/fabric/msp/ ./backup/msp/$ORDERER_CONTAINER
#3. Remove the ordering node container.
docker rm -f $ORDERER_CONTAINER
#4. Launch a new ordering node container using the relevant image tag.
docker run -d -v ${PWD}/backup/orderer/$ORDERER_CONTAINER/:/var/hyperledger/production/orderer/ \
-v ${PWD}/backup/msp/$ORDERER_CONTAINER/:/etc/hyperledger/fabric/msp/ \
--env-file ./envord.list \
--name $ORDERER_CONTAINER \
hyperledger/fabric-orderer:$IMAGE_TAG orderer
After I execute the last command I get:
b0d56da4a9f082bc7c5c0dea1e81ba3bf30c55be8f306b0a27986c706a056da4
The container is created but fails to start with the error presented above. Any clues?

Answer 1

I found the problem. When I exported the variables from the orderer container before bring it down for the update, for some reason they where saved as follow:
ORDERER_GENERAL_EXAMPLE='example value'
The values for all variables were enclosed between single quotes. I removed those single quotes and the problem was solved.
