The following table contains common errors when uploading shapefile data from QGIS to GRID. Table 3 contains example images of each error. Once an error has been corrected it is a good idea to delete the offending zip folder.
Table 2: Troubleshooting.
| Error Message |
Cause | Solution | |
| 1 | This field cannot be null. | Mandatory field has been left blank | Find the blank cell in the attributes table and fill it in |
| 2 | Value ‘____’ is not a valid choice. | Typo in a selection field. | The spelling and punctuation must match that of the Legend, e.g. ‘good’ not ‘Good’. |
| 3 | Duplicate spreadsheet ID found __ | ID field has a duplicate. | All IDs must be unique. Change IDs to be unique in the Attributes table and between templates of the same activity. |
| 4 | ____ is missing the following columns: | File name is different to the original. | All files within the compressed folders must maintain their original name. Navigate to your folder location, rename the incorrect file accordingly, then re-zip the files. |
| 5 | Cannot find ____ | Nested folder – the files have been placed in a folder and then that folder has been zipped. | GRID will not recognise a folder that has been zipped. Select all the files you wish to upload and then zip them (see example photo 5). |
| 6 | 500 Internal Server Error The server encountered an error and could not complete your request. |
Columns have been re-ordered or additional column/s have been added in QGIS. This can occur when running processes in QGIS or by manually adding new fields. | If a process has been run on the template check no additional columns have been added to the attributes, ordering of fields/columns have not changed, etc. Remove any columns in the Attributes table that are not in Legend.xls. |
| 7 | Copying and pasting from Word, resulting in invisible special characters. | ||
| 8 | Geometry is not within the bounds of the Geocentric Datum of Australia 1994 | Geometry was either given incorrect coordinates outside of Australia or intentionally placed overseas | Only upload geometry inside of the Geocentric Datum of Australia 1994. If geometry is outside of this datum it must be manually created inside of GRID. |
Examples of Common Errors
Table 3: Troubleshooting – examples of common errors.
| 1 |  |
 |
|
| 2 |  |
The ‘g’ in good has been capitalised, which does not match the selection options for that field as depicted in Legend.xls |
|
| 3 |  |
IDs must be unique in the Attributes table and between templates of the same activity. |
|
| 4 |  |
The file name has been changed from Activity_Testing_Line.dbf to Activity_Testing.dbf. File names must remain the same. |
|
| 5 |  |
| This error is caused by compressing a folder instead of individual files:
The correct method is to select the individual files you would like and compress them:
|
|
| 6 |  |
An extra column has been created (in this example, when calculating polygon areas). |
|
| 8 |  |
| This error is caused by creating geometry outside of the Geocentric Datum of Australia 1994 (shown below):
The correct method is to only upload geometry inside of this boundary. Anything outside should be manually created inside of GRID. |
