Connect to Elasticsearch from Angular with Cloud functions.

I need a functional version of part 13 of the series Real World App: [login to view URL] You can find the files here at Github: [login to view URL] I will only accept bids at max 100$ (fees excluded) The app with part 13 should be created in Angular7, Firebase RTD, Blaze subscription, cloud functions, connection to a Elasticsearch Server Google Cloud Compute Engine (installed with free Google Cloud tier) My cloud functions error messages are: 1) No index of questions Trace: [index_not_found_exception] no such index, with { resource.type="index_or_alias" & resource.id="questions" & index_uuid="_na_" & index="questions" } at /user_code/server/functions/[login to view URL]:21 at process._tickDomainCallback (internal/process/[login to view URL]:7) Which means that the Elasticsearch engine is not indexed, and is not connected to the firebase database. 2) No firebase authorization No Firebase ID token was passed as a Bearer token in the Authorization header. Make sure you authorize your request by providing the following HTTP header: Authorization: Bearer <Firebase ID Token> or by passing a "__session" cookie.
