be standardize error situations

[AdrieneTZ]

• Standardize error situations on each route, the form is:

  res.status(code).json({
  type: 'categorize error',
  title: 'brief and human-readable description',
  field_errors: {
  key-value pair to point out which the error fields 
  }
  })

• example:

  res.status(400).json({
  type: 'Put record failed',
  title: 'Incorrect data type',
  field_errors: {
  recordId: 'number',
  title: 'string',
  amount: 'number',
  categoryId: 'number'
  }
  })

• Rather than send a long sentence to the front end, pointing out the error fields is an easier way to let the front-end partner know what happened to the sent data.

• Roll back to the initial prisma setting, but still get null as not querying any record in route put record & delete reocrd
• As the reason above, I can't write if (Object.keys(theRecord).length !== 0). I keep figuring out why I can't get {}.
