<<<<<<<<<<<<<<<<<

Cause:
=======
Event contains an extra folder attribuite specified with the null value in expiryAction. For example:
>>>>>>>>>>>>>
  &ltexpiryAction folder="" name="StatsTick_expiryAction" ownerProjectName="AdThRTB" actionText="" conditionText="">
<<<<<<<<<<<<<

'folder=""' attribute here in the expiryAction is unexpected and should not be present.

Resolution:
=========
1). Delete and recreate the event which has the extra empty folder attribute in expiryAction.

2). Open the event with a text editor, find the expiryAction element and remove the folder="" attribute, e.g.:
>>>>>>>>>>>>>
  &ltexpiryAction name="StatsTick_expiryAction" ownerProjectName="AdThRTB" actionText="" conditionText="">
<<<<<<<<<<<<<
