Dotwalking error: checkCompletionOfActivities ## Cannot find function isValid in object... - Known Error

Dotwalking error: checkCompletionOfActivities ## Cannot find function isValid in object... Description It is not guaranteed that a dotwalk reference is a GlideRecord so dotwalking "this._grContext.hr_case" and invoking isValid() will not work. When evaluating it will return the following error "checkCompletionOfActivities ## Cannot find function isValid in object..."

Steps to Reproduce

1. Create a lifecycle event 2. Complete an activity in the lifecycle event 3. This should trigger the subflow "Check activity and wait for event" 4. Subflow should complete with error, "checkCompletionOfActivities ## Cannot find function isValid in object...".

Workaround Workaround:

A workaround here is to rework the logic around dotwalking and utilizing getRefRecord() and isValidRecord().

Original:

…

updateCaseTodoCount: function(caseGr) {

var caseId;

if (!gs.nil(caseGr) && caseGr.isValid())

caseId = caseGr.getUniqueValue();

else if (!gs.nil(this._grContext.hr_case) && this._grContext.hr_case.isValid())

caseId = this._grContext.hr_case.getUniqueValue();

…

New:

…

updateCaseTodoCount: function(caseGr) {

var caseId;

var hrCase = this._grContext && this._grContext.hr_case ? this._grContext.hr_case.getRefRecord() : '';

if (!gs.nil(caseGr) && caseGr.isValid() && false)

caseId = caseGr.getUniqueValue();

else if (!gs.nil(hrCase) && hrCase.isValidRecord())

caseId = hrCase.getUniqueValue();
