LAB 8 - chaincode invocation fails as it seems not to be installed

I just checked that after the commit I don't see any additional container in the system... it should raise a container for each committed chaincode, right?

bash-5.0# peer lifecycle chaincode querycommitted -C allarewelcome -n sacc
Committed chaincode definition for chaincode 'sacc' on channel 'allarewelcome':
Version: 1.0, Sequence: 1, Endorsement Plugin: escc, Validation Plugin: vscc, Approvals: [Org1MSP: true, Org2MSP: true]

Many thanks for your help @Bobbijn The error trace is then a little bit confusing as it's saying that chaincode is not installed. If it was a problem related to the policy set I would expect to see a trace complaining about something related to the approvement of the chaincode.

In any case I've followed your suggestion and I've repeated all the process ensuring that chaincode is approved by Org1 and Org2 (Org2MSP env correctly set):

bash-5.0# peer lifecycle chaincode checkcommitreadiness --channelID \

allarewelcome --name sacc --version 1.0 --sequence 1 --output json

{
"approvals": {
"Org1MSP": true,
"Org2MSP": true
}
}

Committed chaincode definition for chaincode 'sacc' on channel 'allarewelcome':
Version: 1.0, Sequence: 1, Endorsement Plugin: escc, Validation Plugin: vscc, Approvals: [Org1MSP: true, Org2MSP: true]

The problem persists:
Error: endorsement failure during invoke. response: status:500 message:"make sure the chaincode sacc has been successfully defined on channel allarewelcome and try again: chaincode definition for 'sacc' exists, but chaincode is not installed"

Thanks in advance!
