getToken error

I just followed the instructions here
https://firebase.google.com/docs/cloud-messaging/js/receive?authuser=0&hl=en#web-version-9
i get this error when using getToken
`
FirebaseError: Installations: Create Installation request failed with error "400 INVALID_ARGUMENT: Request contains an invalid argument." (installations/request-failed).
at getErrorFromResponse (common.ts:53:1)
at async createInstallationRequest (create-installation-request.ts:77:1)

`

Start with the Firebase Cloud Messaging web receive documentation linked in the report and reproduce the getToken failure. Trace the reported stack from getToken.ts through create-installation-request.ts and common.ts, using the 400 INVALID_ARGUMENT response to identify the missing or invalid request input; done means getToken completes successfully under the documented setup.
