Cannot generate refresh token. "missing 'type' field in credentials"

[hoffmanmc]

I am trying to set up a connection to the Google Ads API as per these instructions..

However, when I run:
oauth2l fetch --type oauth --credentials credentials.json --scope adwords --output_format refresh_token
I recieve the error:
missing 'type' field in credentials

I've tried adding the --type flag and specifying oath to no avail. I also tried specifying "type" at the top level of the object, which returned the error: unknown credential type: "oauth"

I installed using the tar file, running on Linux.

let me guess, your OAuth client credentials.json got generated for 'web application' as I did.

You have to generate one for 'desktop application' (even you're working on a web application) as this tool here does only support credentials made for 'desktop application'.
