Are you facing challenges with your ‘service desk’ template app? You’re not alone. Template apps, while useful, can sometimes experience errors. Thankfully, there’s the ‘app checker’ tool to our rescue. This post will guide you on how to effectively use this tool to diagnose and rectify the issues that arise in your Power Apps.

The Inherent Problems with Template Apps

One of the major challenges with template apps is the hidden data panel, which makes it arduous to refresh or add new data sources. Even adding new columns to tables can become a cumbersome task. A remedy involves extracting the source code, tweaking the manifest settings, and rebuilding the app, which might be daunting for newbies.

Beyond this, the evolving nature of the Power Apps platform sometimes causes inconsistencies. There have been instances where template apps lag behind these platform updates, leading to functionality issues. Microsoft seems to have retired certain templates, especially those with lesser usage, but this results in the disappearance of potentially valuable apps.

Fixing the Service Desk Template with App Checker

Recently, an update in Power Apps led to issues in the service desk template. Let’s understand how to identify and rectify these using the ‘app checker’.

Upon creating an app with the service desk template, you might encounter various errors. To start troubleshooting, click on the app checker icon located at the screen’s top. This reveals a summary of all the errors in the app. One by one, these errors can be addressed and resolved.

Most errors, especially from the ‘app checker’, are found on the ‘tickets page’. Here, gallery template controls show syntax errors when referencing data fields. To correct this, prefix data fields with the “ThisItem” keyword. For instance, prefix ‘AssignedTo’ with “ThisItem” like this:


Similarly, on the “filter page”, the error “Name isn’t valid. This identifier isn’t recognized” appears because the label control is inside a gallery. Again, adjust the syntax to incorporate the ThisItem keyword:


Other errors found on the status, assign, area, and priority pages revolve around the missing “ThisItem” keyword. Rectifying these will ensure the app functions smoothly.
