Unwanted undefined key in object

Starting from an array like this:

    gridColumns =
    [
      { field: "exam_Internalcode", title: 'Exam ID' },
      { field: "patient", title: 'Patient Name' },
  ]

    gridColumns =
    [
      { field: "exam_Internalcode", title: 'Exam ID' },
      { field: "patient", title: 'Patient Name' },
  ]

    gridColumns =
    [
      { field: "exam_Internalcode", title: 'Exam ID' },
      { field: "patient", title: 'Patient Name' },
  ]

    gridColumns =
    [
      { field: "exam_Internalcode", title: 'Exam ID' },
      { field: "patient", title: 'Patient Name' },
  ]

And an array like this

  gridData = [
    { exam_Internalcode: 'I-12M4', patient: 'Mark Lenner', idblock: 125 },
    ...
  ]

  gridData = [
    { exam_Internalcode: 'I-12M4', patient: 'Mark Lenner', idblock: 125 },
    ...
  ]

  gridData = [
    { exam_Internalcode: 'I-12M4', patient: 'Mark Lenner', idblock: 125 },
    ...
  ]

  gridData = [
    { exam_Internalcode: 'I-12M4', patient: 'Mark Lenner', idblock: 125 },
    ...
  ]

What's the best way to obtain an array like this?

result = [
  {'Exam ID': 'I-12M4', 'Patient Name': 'Mark Lenner'} //no idblock because there is no field for it in gridColumns 
  ...
]

result = [
  {'Exam ID': 'I-12M4', 'Patient Name': 'Mark Lenner'} //no idblock because there is no field for it in gridColumns 
  ...
]

result = [
  {'Exam ID': 'I-12M4', 'Patient Name': 'Mark Lenner'} //no idblock because there is no field for it in gridColumns 
  ...
]

result = [
  {'Exam ID': 'I-12M4', 'Patient Name': 'Mark Lenner'} //no idblock because there is no field for it in gridColumns 
  ...
]

However, I get an undefined key and I don't understand why
