Any update on this error?

We have fixed this v1.5.8-RC-up-apk by updating the following line of code. By replacing the Counter class to Counters
File location : Project-Saral/v1.0/backend/src/models/counter.js

Current code:

    let match ={ 
        _id: counterOfName
    }
    let update = { $inc: {counter_value: 1} }
    let options = { upsert: true, 'new': true  } ;
    const seqData = await Counter.findOneAndUpdate(match,update,options)
    return seqData.counter_value
} 

Changes we did in code:

    let match ={ 
        _id: counterOfName
    }
    let update = { $inc: {counter_value: 1} }
    let options = { upsert: true, 'new': true  } ;
    const seqData = await Counters.findOneAndUpdate(match,update,options)
    return seqData.counter_value
}
