ArcPy: Grid Index Features freezing and crashing ArcGIS Pro

Question

I am trying to use the grid index features tool in ArcPy. However when I run it outside of the Python window in ArcGIS Pro, it freezes and crashes. When used within ArcGIS Pro it works fine. I am using version 2.9.

This is how the code looks:

import arcpy
import os

def gridIndex(outputLocation, siteBoundary, mapScale, mapWidth, mapHeight):
    """This definition will create a grid index for map series within ArcGIS Pro
       and add some custom fields to it.

    Arguments:
    outputLocation (string): The location of where the gridindex feature class has to be output.
    siteBoundary   (file): The site boundary feature class, to determine the border.
    mapScale       (integer): The scale in which the map series need to be displayed.
    mapWidth       (integer): The width of the index squares in cm.
    mapHeight      (integer): The height of the index squares in cm.

    Return:
    originalGridIndex (file: This is the feature class containing the grid
    """
    originalGridIndex = arcpy.cartography.GridIndexFeatures(os.path.join(outputLocation, "gridIndexs"), siteBoundary, "", "", mapScale, mapWidth, mapHeight)
    arcpy.management.AddField(originalGridIndex, "Scale", "LONG")
    arcpy.management.AddField(originalGridIndex, "FigureReference", "TEXT", 10) #SQL Query
    arcpy.management.AlterField(originalGridIndex, "PageName", "PageSort", "PageSort")
    arcpy.management.AddField(originalGridIndex, "PageName", "TEXT", 50)
    return originalGridIndex

def fillFields(gridIndexFC, mapScale):
    """This definition will take the grid index made in gridIndex and fill the fields
       that still need filling in.

       Arguments:
       gridIndexFC (file): This is the grid featureclass used for the map series.
       mapScale    (integer): This is the scale used for the map series.
       """
    arcpy.management.CalculateField(gridIndexFC, "Scale", mapScale)

def main():
    """This script will create a grid index within a site boundary.
       It will then add some custom fields to this feature class and fill some fields.
       This grid will be used for the map series within ArcGIS Pro.

       Arguments:
        outputLocation (string): The location of where the gridindex feature class has to be output.
        siteBoundary   (file): The site boundary feature class, to determine the border.
        mapScale       (integer): The scale in which the map series need to be displayed.
        mapWidth       (integer): The width of the index squares in cm.
        mapHeight      (integer): The height of the index squares in cm.

        Output:
        A grid index ready to be used in map series."""
    siteBoundary = arcpy.GetParameter(0)
    outputLocation = arcpy.GetParameterAsText(1)
    mapScale = arcpy.GetParameter(2)
    mapHeight = arcpy.GetParameter(3)
    mapWidth = arcpy.GetParameter(4)
    grid = gridIndex(outputLocation, siteBoundary, mapScale, mapWidth, mapHeight)
    fillFields(grid, mapScale)

if __name__ == '__main__':
    main()

Because it freezes and crashes, I can't find an error message and therefor I can't fix it. Any ideas?

All your input parameters are set to the first input [GetParameter(0)]. They should look more like this:

siteBoundary = arcpy.GetParameterAsText(0)
outputLocation = arcpy.GetParameterAsText(1)
mapScale = arcpy.GetParameter(2)
mapHeight = arcpy.GetParameter(3)
mapWidth = arcpy.GetParameter(4)
