# Troubleshooting

- [Column ID (Dev Mode)](https://help.docexport.com/troubleshooting/column-id-dev-mode.md): If you have trouble populating columns (e.g. too long titles or special characters), you can use the column ID instead.
- [App Permission](https://help.docexport.com/troubleshooting/app-permission.md): DocExport needs access to source boards if you're using mirror columns or formulas which load data from other boards in different workspaces.
- [Authorize App](https://help.docexport.com/troubleshooting/authorize-app.md): By default, our system uses short-lived API tokens for generating documents, which work well for most use cases.
