Instantiate Chaincode error: 500

I'm following the steps provided on README but there was an error
when trying to instantiate the chain code:

Instantiate the chaincode:

root@f2d3b8665efe:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode instantiate \
	-o orderer.example.com:7050 \

	-C mychannel \
	-n fabcar \
	-v 1.0 \
	-c '{"Args":["init"]}'

Error:

I've searched on the web but I couldn't find much.

I'm using macOS Big Sur 11.5.2, and Docker 4.1.0 .

It seems to be a Docker problem, related to that version on macOS. At StackOverflow someone said they had
to downgrade Docker to version 2, and then it worked.

If anyone has a workaround, please let me know.
