testing lua script with "0" throws luaUpdater.validation.empty_test_value exception

[mbraeuner]

Hi there,

is there a reason to test the input value with empty()

There is no possibility to test with 0 as input
An empty string could be a nice test case for scripts.
A nil value as well. Maybe a second button to test nil/null values would be nice.

Best Regards,
Marco
