Error "Something went wrong" when loading Data Capture forms in Field Service mobile app

Publish Date: Jun 12, 2026
Description
Problem

When opening a Data Capture form in the Field Service mobile app, the form may fail to render. Users see an endless loading spinner or a "Something went wrong" error, and form fields and layout do not appear. The issue consistently affects the same form or record type.

 
Cause

Form initialization through Lightning Data Service (LDS) and Lightning Web Components (LWC) can be blocked by one or more of the following:

  • The Field Service Integration permission set is missing required field access
  • Validation rules or lookup filters interfere with form rendering
  • Required objects or fields are absent from the briefcase configuration
  • The mobile device has outdated metadata cache
Resolution
Resolution

These failures are caused by configuration or cache issues. Work through the steps below in order to identify and resolve the root cause.

1. Verify Field-Level Access

  1. Go to Setup → Permission Sets → Field Service Integration
  2. Review field permissions for Service Appointment or Work Order
  3. Confirm all fields used by the Data Capture form have Read and Edit access


2. Review Validation Rules and Lookup Filters

  1. Check validation rules and lookup filters on the target object
  2. Temporarily disable rules that reference form fields and retest
  3. Re-enable rules one at a time to identify the problematic rule, then refine it


3. Verify Briefcase Configuration

  1. Confirm all required objects and custom fields are included in the briefcase
  2. Save changes and trigger a mobile sync


4. Clear Mobile Cache

  1. Open the Field Service mobile app settings
  2. Select Clear Cache or Clear Offline Data
  3. Re-sync the app and retest the form


NOTE: Cache-clearing options vary by platform (iOS/Android) and app version. Briefcase updates may take several minutes to sync to mobile devices. Validation rules that are required for other business processes should be refined rather than permanently disabled.
