How to generate a source map in the monorepo? - vue.js

Question

I am new to monorepo.
The thing is they want me to upload a sourcemap to the rollbar.
But I don't know how to generate one.
When I ask for help they told me to read documents. I read the documents / watch Youtube videos for long time but i am still not clear about generating the source map.
In our monorepo we got lots of project
apps
- ProjectA
- ProjectB
- ProjectC
- ProjectD
The thing is i want to generate source map for the ProjectC.
To generate the source map I think i need to build the project ( tell me if i am wrong )
so I look into the project.json. But I don't see the build command.
{
"$schema": "../../node_modules/nx/schemas/project-schema.json",
"sourceRoot": "apps/ProjectC",
"projectType": "application",
"targets": {
"lint": {
"executor": "#nrwl/linter:eslint",
"outputs": ["{options.outputFile}"],
"options": {
"lintFilePatterns": ["apps/ProjectC/src/**/*.ts"]
}
},
"test": {
"executor": "#nrwl/jest:jest",
"outputs": ["coverage/apps/ProjectC"],
"options": {
"jestConfig": "apps/ProjectC/jest.config.ts",
"passWithNoTests": true
}
}
},
"tags": []
}
How can i configure so that it will produce a sourcemap file? ProjectC is a vue app.
The thing is in the tsconfig.app.json. I see the configuration like this. But I don't find the source map. Is this file related to generating source map?
