The error message suggests that there is an issue with updating a specific field, "Opp_Submit_Date__c" in this case. The error points to a problem with field-level security settings or permissions. Let's dive into the steps to resolve this error.
Sample Error log --
UpdateRecordFunc Error -> {"status":400,"body":{"message":"An error occurred while trying to update the record. Please try again.","statusCode":400,"enhancedErrorType":"RecordError","output":{"errors":[],"fieldErrors":{"Opp_Submit_Date__c":[{"constituentField":null,"duplicateRecordError":null,"errorCode":"INVALID_FIELD_FOR_INSERT_UPDATE","field":"Opp_Submit_Date__c","fieldLabel":"Opportunity Submit Date","message":"Unable to create/update fields: Opp_Submit_Date__c. Please check the security settings of this field and verify that it is read/write for your profile or permission set."}]}}},"headers":{},"ok":false,"statusText":"Bad Request","errorType":"fetchResponse"}
Step 1: Check Field-Level Security Permissions:
Log in to your Salesforce org and go to the Object Manager.
Locate the object that contains the field "Opp_Submit_Date__c."
Click on the field and check its Field-Level Security settings.
Ensure that your profile or permission set has both "Read" and "Edit" permissions for the field.
Step 2: Add the Field to a Page Layout (Most Important):
Sometimes, even if you don't plan to display the field on a page layout, adding it temporarily to a layout for your profile can help resolve issues related to updating the field via code.
Step 3: Verify Field Accessibility:
Confirm that the field has the correct "Field Accessibility" settings. It should be marked as "Visible" for your profile.
Step 4: Profile and Permission Set Considerations:
Ensure you are using the correct profile or permission set when testing your LWC component. Permissions can vary depending on your specific profile or permission set.
