This difference is usually caused by user context and permissions. Even though Flows can run in system context, they still respect field-level security and sometimes record-level access, especially in screen Flows. Admins typically have full access, which hides these issues during testing.
Another factor is that referenced records or lookup relationships may not be visible to standard users. When a Flow tries to read or update something the user can’t access, the logic may silently skip or fail without a clear error.
The safest approach is to test Flows using real user profiles and explicitly configure run context.
Takeaway: Always test Flows with the same permissions your end users have.
Why does my Salesforce REST API return 403 Forbidden?
The connected app or user lacks required permissions. Problem Explanation Salesforce enforces OAuth scopes, object access, and IP restrictions on API calls. Root Cause(s) 1. Missing API Enabled permission 2. Insufficient OAuth scopes 3. IP relaxation not configured Step-by-Step Solution 1. Verify usRead more
The connected app or user lacks required permissions.
Problem Explanation
Salesforce enforces OAuth scopes, object access, and IP restrictions on API calls.
Root Cause(s)
1. Missing API Enabled permission
2. Insufficient OAuth scopes
3. IP relaxation not configured
Step-by-Step Solution
1. Verify user profile permissions
2. Check Connected App OAuth scopes
3. Review IP relaxation settings
Edge Cases & Variations
1. Community users have limited API access
2. Named Credentials simplify auth issues
Common Mistakes to Avoid
1. Using wrong user for integration
2. Ignoring permission sets

Write focused test classes that cover all trigger paths.
Problem Explanation
Salesforce requires 75% overall coverage and trigger execution during deployment.
Root Cause(s)
1. Missing test data
2. Trigger logic depends on existing records
3. Unhandled branches
Step-by-Step Solution
1. Create test data inside
@testSetup2. Cover insert, update, delete scenarios
3. Assert outcomes
Edge Cases & Variations
1. Flow-triggered logic also needs coverage
2. SeeAllData=false may hide dependencies
Common Mistakes to Avoid
1. Relying on org data
2. Ignoring negative test cases
See lessWhy does my LWC show “Cannot read properties of undefined” when loading data?
The JavaScript tries to access data before the wire or API response is available. Problem Explanation LWCs render before async data arrives.

The JavaScript tries to access data before the wire or API response is available.
Problem Explanation
LWCs render before async data arrives. Accessing nested fields without checks causes runtime errors.
Root Cause(s)
1. Missing null checks
2. Incorrect API response shape
3. Wire method not returning expected fields
Step-by-Step Solution
1. Use optional chaining (
?.)2. Guard rendering with
if:true3. Log the response structure in
wiredResultget accountName() {
return this.accountData?.Name;
}
Edge Cases & Variations
1. Imperative Apex calls need manual loading states
2. Cacheable Apex may return stale data
Common Mistakes to Avoid
1. Assuming data exists on first render
2. Accessing nested objects blindly
See lessWhy does my Salesforce Flow fail with “UNABLE_TO_LOCK_ROW” during bulk updates?
Multiple processes are trying to update the same record at the same time. Problem Explanation Salesforce locks records during updates. When Flows, triggers, or integrations attempt concurrent updates, the database prevents conflicts by throwing a row lock error. Root Cause(s) 1. Parallel Flow intervRead more
Multiple processes are trying to update the same record at the same time.
Problem Explanation
Salesforce locks records during updates. When Flows, triggers, or integrations attempt concurrent updates, the database prevents conflicts by throwing a row lock error.
Root Cause(s)
1. Parallel Flow interviews updating same record
2. Batch or integration running simultaneously
3. Parent–child record updates in loops
Step-by-Step Solution
1. Reduce record updates inside loops
2. Move non-critical updates to scheduled paths
3. Ensure parent records are updated once per transaction
4. If using Apex, retry logic with Queueable Apex
Edge Cases & Variations
1. More common in high-volume orgs
2. Record-triggered Flows on parent objects amplify locking
Common Mistakes to Avoid
1. Updating the same record repeatedly
2. Ignoring scheduled paths for heavy updates
See lessWhy does my Salesforce dashboard show different data for different users?
The dashboard runs under a specific running user context. Problem Explanation Dashboards respect the running user’s permissions and sharing, unless set to dynamic. Root Cause(s) 1. Dashboard running user mismatch 2. Private sharing model 3. Field-level security differences Step-by-Step Solution 1. ERead more
The dashboard runs under a specific running user context.
Problem Explanation
Dashboards respect the running user’s permissions and sharing, unless set to dynamic.
Root Cause(s)
1. Dashboard running user mismatch
2. Private sharing model
3. Field-level security differences
Step-by-Step Solution
1. Edit dashboard properties
2. Set running user to “Dynamic”
3. Verify user permissions
Edge Cases & Variations
1. Scheduled refresh uses running user
2. Joined reports behave inconsistently
See lessWhy does my Flow update fail silently without errors?
The Flow’s update criteria doesn’t match any records. Problem Explanation Salesforce doesn’t throw errors when zero records are updated. Root Cause(s) 1. Incorrect filter logic 2.

The Flow’s update criteria doesn’t match any records.
Problem Explanation
Salesforce doesn’t throw errors when zero records are updated.
Root Cause(s)
1. Incorrect filter logic
2. Variable mismatch
3. Null values
Step-by-Step Solution
1. Debug Flow with sample records
2. Log record IDs before update
3. Add fault paths for visibility
Edge Cases & Variations
1. Before-save flows behave differently
2. Bulk record-triggered flows need testing
Common Mistakes to Avoid
1. Assuming update always succeeds
2. Skipping debug logs

The running user lacks record-level access.
Problem Explanation
LWCs run in user context, while Developer Console often runs with elevated access.
Root Cause(s)
1. Missing sharing rules
2. Apex class marked
with sharing3. Field-level security restrictions
Step-by-Step Solution

2. Review sharing model
3. Adjust Apex sharing if appropriate
Edge Cases & Variations
1. System context applies only to Apex, not LWC
2. Guest users have additional limits
Common Mistakes to Avoid
1. Removing sharing without justification
2. Testing only as admin
