1. Is this a client library issue or a product issue?
   This is a client library issue I found by just following the documentation for exporting cloud firestore data.

2. Did someone already solve this?
   No

3. Do you have a support contract?
   No

Environment details

• OS: Cloud Function
• Node.js version: 10
• npm version:
• google-gax version: ^2.2.0

Steps to reproduce

1. execute de cloud function with documentation's given code
2. see the error:

TypeError: Cannot read property 'toString' of undefined at PathTemplate.render (/workspace/node_modules/google-gax/build/src/pathTemplate.js:110:37) at FirestoreAdminClient.databasePath (/workspace/node_modules/@google-cloud/firestore/build/src/v1/firestore_admin_client.js:962:56) at exports.scheduledFirestoreExport (/workspace/index.js:7:31) at Promise.resolve.then (/layers/google.nodejs.functions-framework/functions-framework/node_modules/@google-cloud/functions-framework/build/src/invoker.js:199:28) at process._tickCallback (internal/process/next_tick.js:68:7)

Just found out that the suggested code snippet was using process.env.GCLOUD_PROJECT, but it was null, even on GCP environment. Weird.

@jgcmarins I'm getting this same error after upgrading this backup function to Node10.

How did you fix it?

ah, according to this best option is to hardcode the project name. 👍

I also hard-coded and it got resolved, but it is not an acceptable approach. Does anyone have other thoughts?
