Error Message Invalid update: Match not found, reset to original

[Jehiellb]

Hi ServiceNow Community,

Have you experienced this kind of error? Upon updating this form this error will occur.
It says Invalid update: Match not found, reset to original.

I have no idea why am I having this kind of error specifically in location/country field.

Do you have any idea what is the root cause of this issue and how can I fix it?

Your help will be much appreciated. Thanks!

Hi Jehiellb,

Looks like there might a subtask in opens state. 

There should be a business rule checking for subtask is in the closed or open state. 

Please let me know if you have any questions

Thanks and Regards,

First hint for me is that its providing you a field message.  That means its probably not OOB.  
Check the client scripts of the table you're on and look for that message specifically in the script.

I think it is because of invalid value assigned to reference field.

First check  the filled value in location  is valid or not.

Check the scripts which is setting value of a reference field 

While setting the value of reference through client script,

we should set both value and display value like the below

g_form.setValue('u_field_reference', value, displayValue) ;

It is a best practice to follow and it will fix this issue.
