Transform functions with Algolia firestore extenstion

[dejiemiabata]

I am trying to utilise the transform functions option within Algolia. I have tried the following to no avail and I keep getting errors such as “unexpected token < in json”.

Basically, my posts collection has a userId field which I am trying to transform before sending to algolia. The transformed function should grab the userId field and output data from the users collection.

Below you can see the transform function I am testing out + errors.

I tried using the reference here: https://github.com/algolia/firestore-algolia-search. Is there a better example for how to use transformFunctions in algolia ?

export const transformPosts = functions.region("us-central1").https.onCall(async (payload) => {
  const { userId: userIds } = payload
  const userId = await localFirestore.collection("users").doc(userIds).get()
  return { userId }
})

it seems that the post request is being redirected to a Google login page which returns html but the request is expecting json

[dejiemiabata]

@i14h okay do you know the right approach to creating a transform function that will work with algolia search ?

[smomin]

@dejiemiabata Try creating a function that allows unauthenticated invocations.

[dejiemiabata]

@smomin I have allowed unauthenticated invocations but the error still persists. Also, just noticed that by default, callable functions have the invoker set to public

[dejiemiabata]

@smomin still not working

[smomin]

I am looking into it. I will let you know my findings.

@smomin I noticed the PROJECT_ID was pointing to the wrong project. Sorry for the confusion here.
