The parameter type '==="' cannot be assigned to the 'WhereFilterOp' type in this argument

I'm currently working on creating a where clause for a firebase collection reference:

this.allItineraries = firebase
            .firestore()
            .collection(`itinerary`);

Here is the issue with the where clause:

      return this.allItineraries.where('userId', '===', this.userId);

However, when attempting to compile the program, an error occurs:

[ng] ERROR in src/app/services/data.service.ts(45,55): error TS2345: Argument of type '"==="' is not assignable to parameter of type 'WhereFil

This problem arises even though the structure of the where clause seems correct based on firebase's examples.

Answer №1

Attempting to execute the query directly on the collection reference caused an issue for me. I found success by first creating a query from the collection and then using that specific query for the onSnapshot method.
