Autograding: Fail to Build & Test

[Ingsuifon]

After passing the test of proj1 on my local machine, I push my commit and encounter the problem in the Build & Test stage:

. . . // omit some output
go: finding github.com/spf13/pflag v1.0.3
go: finding sigs.k8s.io/yaml v1.1.0
go: finding gopkg.in/yaml.v2 v2.2.4
go: finding github.com/pingcap/check v0.0.0-20200212061837-5e12011dc712
Checking formatting
./kv/server/raw_api.go
./kv/storage/standalone_storage/standalone_storage.go
Error: make: *** [Makefile:47: ci] Error 1
Error: Process completed with exit code 2.

How can I resolve it?
