My Problem

I am getting an error ONLY when doing gcloud builds submit. My build is working locally and when creating a docker image locally. I am assuming that this is a problem where a file is not getting copied into the tarball correctly; however, in my debugging I found that it appears it is being copied.

My error:

Type error: Parameter 'service' implicitly has an 'any' type

Which is from some code that looks like this:

const {
    firestore,
    collections: {
      rentals: { services },
    },
  } = useFirebaseCtx();
const newServiceEvents = services.map((service, index) => {
   ...
})

Where useFirebaseCtx is extensively typed (with no explicit any inside it)

services has an explicit type of Organizations.Rentals.Services.Flat[]

Debugging I have tried

1. When I run yarn run eslint . --ext .js,.jsx,.ts,.tsx I do not get any errors

2. When I run docker build -t my-docker-image-name . I do not get any errors (and the image builds to completion)

3. I have confirmed (by running gcloud meta list-files-for-upload) that my type folder is indeed being uploaded in the tarball

Abbreviated output of gcloud meta list-files-for-upload:

...
types/organizations/index.d.ts <- this is the file the type is defined in
...
