Can't deploy to Heroku: "error: Module not found"

[diguifi]

Hi! I've been using this buildpack for over a year now, but these last months, I can't seem to deploy.
Everytime I get this error on the build log:

error: Module not found "https://deno.land/std/ws/mod.ts".
    at file:///app/server.ts:2:45

Well, you might think "maybe you're a dumass and you should remove this non-existent dependency "ws/mod.ts" from your file server.ts at line 2"
But, there's no such dependency, heres my latest server.ts file.

I tried a lot of things, I checked and re-checked a lot of things, I even completely removed a dependency that in the end had nothing to do with the error.

Another very weird thing is, I tryed re-deploying the same branch, without changin anything and the build log gave me the same error, but in a different file (which is also not calling that dependency "ws/mod.ts" anywhere)

error: Module not found "https://deno.land/std/ws/mod.ts".
    at file:///app/server/clientHandler.ts:1:50

My last resort is coming here to ask for help.

Just in case it helps, here the entire build log:

Could you try removing "--cached-only" option in the Procfile?

as a side note, I felt as if the build was suspiciously fast
