Description
@angular-devkit/build-angular@12.2.13 depends on @ampproject/remapping@1.0.1, which is affected by this blocking issue: ampproject/remapping#153
The issue was quickly fixed and a new version @ampproject/remapping@1.0.2 was released just yesterday.
Like reported in the linked page, the issue affects all the projects having at least one library containing at least one .js file made up of just a source map and no additional content. In my specific case, the impacted library is @zxing/browser@~0.0.10:

Due to the blocking nature of the issue, I kindly ask you to publish a new patch version which depends on the fixed version of @ampproject/remapping.
馃敩 Minimal Reproduction
Just launch ng build on a project which depends on @angular-devkit/build-angular@12.2.13 and, for example, @zxing/browser@~0.0.10 (like in my screenshot)
馃敟 Exception or Error
Like reported on the linked issue, the following error is displayed:
./node_modules/ - Error: Module build failed (from ./node_modules/@angular-devkit/build-angular/src/babel/webpack-loader.js):
Error: Transformation map 0 must have exactly one source file.
Did you specify these with the most recent transformation maps first?
