fetch method not working properly

[ghost]

db.fetch({'phoneNumber': '07011111111'})

I want to fetch with a phone number, but when I fetch with a matching value, I don't get the correct result.
0 results

Are you storing your phone numbers as strings? Try getting the item by key and compare the returned data with your fetch query.

You better use get() method rather than fetch() when you retrieve only one item. If you use Node.js, don't forget to use "await" keyword, otherwise, you will get a promise object.

// get one record {key:'xxxxxx', 'phoneNumber': '07011111111'} with the key or id ''xxxxxx''
const phone_number_record = await db.get("xxxxxxx")

// get an array of one record [ {key:'xxxxxx', 'phoneNumber': '07011111111'} ]
const array_of_phone_number_record = await db.fetch({'phoneNumber': '07011111111'})
