When reporting this error, first look at the go version. Command: go version. See if the version of go is the same as the version you requested. It is not the same to change the version of go.
When the replacement is completed, first ./byfn.sh down, and then ./byfn.sh up to start.
If there is no problem with the go version and still report this error, you must execute the docker images command to check whether the image version matches the version of go. Because the mirror download is not set to the latest version by default, it may not be compatible with your go version.
After the replacement is complete, restart ./byfn.sh down, and then restart ./byfn.sh up.
