RoboTask forum

Hello

There's an error that I've started getting in a RoboTask task. In a text loop I use a BASIC 'Evaluate' function, which is:
Expression to Evaluate: {VARIABLE} + 1
Assign Result to Variable: {VARIABLE}

This was worked successfully over many months in the past. However, over the last three weeks a few times the following error has occurred: E: ... AM: Server execution failed, ClassID: ...

Do you know what this means and how I can avoid it in the future?

Any help would be fantastic.

Thank you in advance

You can use Increment Variable action, if your variable contains an integer value.

Also you can use JS Evaluate or VB evaluate actions.
It seems these actions more stable because they use system native script engine
