Unable to build successfully

i just cloned the project then follow the installation process after that when i try to build i got the following error

[warning] Error when using sourcemap for reporting an error: Can't resolve original location of error.

[warning] Entry module "src/preview/index.ts" is using named and default exports together. Consumers of your bundle will have to use `chunk.default` to access the default export, which may not be what you want. Use `output.exports: "named"` to disable this warning.

also when i try to deploy it to vercel i got the same source map issue

 [warning] Error when using sourcemap for reporting an error: Can't resolve original location of error.
