Ambiguous error message when connecting to Google Data Source

The error was that the proper API Service wasn’t enabled in my google project (In my case the Admin SDK).

I found that out by going to network calls on chrome developer console and looking at the response of the apex remote call.

The response looked like this:

[{"statusCode":200,"type":"rpc","tid":28,"ref":false,"action":"skuid.RemotingStubs","method":"proxy","result":"{\"statusCode\":403,\"status\":\"Forbidden\",\"setCookies\":null,\"headers\":{\"Content-Type\":\"application/json; charset=UTF-8\",\"X-XSS-Protection\":\"1; mode=block\",\"Expires\":\"Fri, 28 Sep 2018 11:22:53 GMT\",\"Vary\":\"Origin,Accept-Encoding;X-Origin\",\"Cache-Control\":\"private, max-age=0\",\"X-Frame-Options\":\"SAMEORIGIN\",\"Accept-Ranges\":\"none\",\"Date\":\"Fri, 28 Sep 2018 11:22:53 GMT\",\"X-Content-Type-Options\":\"nosniff\",\"Server\":\"GSE\",\"Alt-Svc\":\"quic=\":443\"; ma=2592000; v=\"44,43,39,35\"\",\"Transfer-Encoding\":\"chunked\"},\"error\":null,\"body\":\"{\\n \"error\": {\\n  \"errors\": [\\n   {\\n    \"domain\": \"usageLimits\",\\n    \"reason\": \"accessNotConfigured\",\\n    \"message\": \"Access Not Configured.

Shmuel, thank you for closing the loop on this for the Community. Glad you were able to resolve the issue!
