Handling MySQL BIT Data Type in Knex: Conversion from Buffer to Boolean

i am using knex db with mysql in wappler low code software and i have a column in my table and column name is is_active and it have bit datatype ig it means boolean right ?

so when i use select query to return data

it should return data like

is_active : 1 or 0

or may be

is_active : true and false

but it return data like

 "is_active":  {
     "type": "Buffer",
      "data": [ 1 ]
   },
