Hello, we got a weird error message when trying to run the precheck on Efabless platform:
```             [11/06/23 18:17:11 PST] SUBMITTED
            [11/06/23 18:21:27 PST] STARTED
            [11/06/23 18:21:45 PST] EXCEPTION
                Script error code: 1```
Would you please help us to debug this? I have no clue of what is happening. The project is here: https:/repositories.efabless.com/duyhieubui/UNIC-CASS-IC4.git

The problem is because of the submodules. We tried to use the submodule but it does not work with precheck on Efabless platform. We also got this error when using submodule:
```$ git submodule
fatal: no submodule mapping found in .gitmodules for path 'caravel'```
