The Field Service mobile app fails to start due to missing files

  • Artikkeli

This article provides a resolution for an issue where the Dynamics 365 Field Service mobile app fails to start.

Symptoms

When you start using the new user experience in the Dynamics 365 Field Service mobile app, you receive an error message stating that certain files are missing.

Cause

Some required source records are missing. These records should be created when installing the Field Service app, but in rare cases, they aren't created successfully or are corrupted. It's also possible that a user deleted the records.

Resolution

Step 1: Check if the MobileSource table contains data

  1. Go to Power Apps and open the environment you want to check.

  2. Select Tables, select the All filter, and search for the MobileSource (msdyn_mobilesource) table.

  3. Select the table and verify if it contains the following data in the Name column:

    • /card/bookingListViewItem.yml
    • /card/defaultViewItem.yml
    • /card/serviceTaskGridItem.yml
    • /sitemaps/mobile.yml

If there's no data in the table, something went wrong with the solution update.

Step 2: Apply the Field Service solution update again

  1. In Power Apps, open your environment and go to Solutions.

  2. Search for fieldservice_anchor and delete the FieldService_Anchor solution.

  3. Go to the Power Platform admin center and select the environment where you deleted the solution.

  4. In the environment details, under Resources, select Dynamics 365 apps.

  5. Select Install app > Dynamics 365 for Field Service > Next.

  6. Accept the terms of service and select Install.

After you install the solution, verify that the table contains the required data using step 1.
