Argument of type 'import("mongoose").Types.ObjectId' is not assignable to parameter of type 'import("mongoose").Schema.Types.ObjectId'. Type 'ObjectId' is missing the following properties from type 'ObjectId': auto, defaultOptions, OptionsConstructor, cast, and 20 more.ts(2345)

this error is showing when i convert an string objectId to to mongoose Objectid;

  const questId  = new mongoose.Types.ObjectId(questionId as string )
      const response = await this.__questionRepository.createNewAnswer(
        answer,
        questId,// here showing the above typescript  error
        userId,
        userType
      );



//this is how i defined the questionId in Schema

 questionId: {
            type: mongoose.Schema.Types.ObjectId,
            ref: 'Question',
            required: true
        }

• node.js
• typescript
• mongoose
• objectid

• Hello, this is because the questionId might be getting null/undefined so try to check whether it is correct or not. – user28234598 Commented Jan 20 at 12:49
