Hi All,

I am using Version 22.1 robotics studio. execution gets stuck in wait all control. In log i see that the wait is completed, so expected to get timeout execution. But nothing happens. Did anyone else facing this issue?

This issue is specific to this project and i couldnt locate %Appdata% → local->openspan->8.0->projects to clear the files

In previous versions, we have option to clean project/solution that fixes the issue most of the time. How to do it in Version 22.1

@Vivek Ayyakannu The log snippet you posted does not include any automation steps (lines containing “ExecutionLink from” and “propagating from”). These are the yellow and blue lines respectively.

Is it possible to post a screenshot of where you believe it is getting stuck in your automation? Perhaps I can see something you might have missed there.

I would examine the full log and walk through your automation steps. You can use the log playback to do this on your machine and follow through to where it ends. You can also use the find to step through your log looking for the yellow and blue lines. Here is a post that might help as you can create a new file with only the lines you are interested in.

As for your second question; in 22.1, we no longer extract a local copy of the deployment package. It is extracted into memory, so there is nothing to clear from the machine.

@ThomasSasnett Thanks for the response
With ongoing incident ticket, came to know that break point might be causing the issue.
Clearing off the breakpoint, i am able to run the automations.

@Vivek Ayyakannu That makes sense. A breakpoint will halt execution. If you are testing in Studio, it is a good idea to delete all breakpoints when you want to run a test without interference by the debugger.
