I can’t figure out what’s wrong with this as it works perfectly well for another project that I have.
Hi, the file runs properly until the point it reaches the message box activity which then threw the error.
The function of the message box is mainly to pause the project so it can prompt the user to perform an action (i.e. zip a file - I was not able to download custom activity to do this due to firewalls issue) before continuing the actions.
Basically, all the activities under System - Dialog do not work. But it is strange that it is working for another project…
Message box uses Uipath.System.Activities and when I use 21.10.2 I got the same error.
However, when I downgraded the dependency to 20.10.4. the message box worked without an error. You can try this as a workaround.
We are trying to solve this by whitelisting some executables in the uipath.
