[Bug] Surface all errors to Button Message Error on LWC

[Julian88Tex]

Recently, LH reached out and let us know that there are some instances where clicking the button produced no results and error messages. It's been identified that this is caused by a standard Salesforce error being thrown (process builder process, field filter, validation rule, etc.) but is only viewable in logs and not button. As an admin, it is important to know when an error occurs so they can take steps to prevent it or work around it.

Steps to Reproduce:

1. Log into Partial Sandbox
2. Open Debug Console in a separate tab
3. In first tab, navigate to Account "Black El" : https://lovinghouston--partial.lightning.force.com/lightning/r/Account/0011N00001qzT38QAE/view
4. Click "Find Closest Churches" button

Results:

• In tab with debug debug console log shows error in status: Insert failed. First exception on row 8; first error: CANNOT_EXECUTE_FLOW_TRIGGER, We can't save this record because the “CSP Updates” process failed. Give your Salesforce admin these details. This error occurred when the flow tried to update records: INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY: insufficient access rights on cross-reference id: 0031N00001GSDyo. You can look up ExceptionCode values in the SOAP API Developer Guide. Error ID: 563121415-928619 (-636854535): []
• No message is shown next to button

Expected Results:

• In tab with debug debug console log shows error in status: Insert failed. First exception on row 8; first error: CANNOT_EXECUTE_FLOW_TRIGGER, We can't save this record because the “CSP Updates” process failed. Give your Salesforce admin these details. This error occurred when the flow tried to update records: INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY: insufficient access rights on cross-reference id: 0031N00001GSDyo. You can look up ExceptionCode values in the SOAP API Developer Guide. Error ID: 563121415-928619 (-636854535): []
• Above error is shown next to button

ACs Given a process exists that would cause an error when creating Account/CSP records (example "CSP Update") When I click the "Find Closest Churches" button Then appropriate Salesforce error message displays next to button

Given a validation rule exists that would cause an error when creating Account/CSP records When I click the "Find Closest Churches" button Then appropriate Salesforce error message displays next to button

Given a lookup field filter exists that would cause an error when creating Account/CSP records When I click the "Find Closest Churches" button Then appropriate Salesforce error message displays next to button

Given a required field setting exists that would cause an error when creating Account/CSP records When I click the "Find Closest Churches" button Then appropriate Salesforce error message displays next to button
