I am getting the following error. However, It doesn’t make much sense because it worked perfectly yesterday and every day before and is now throwing this error. Nothing has been changed in the code or file paths between runs. Can someone help? I can’t figure out why it randomly cannot access it.

21.10.7+Branch.support-v21.10.Sha.4fc9759469a976c6aff9aff581b459a31fa01cd9

HI @kasey.betts

Can you check if the file is opened in the machine or user

Have you tried with Kill process activity

The file is not open anywhere else. Kill which process? The txt file (so notepad)?

That does not work either

6

Oh it actually works if I move the activity to be done earlier.

Do you know why it might randomly start doing that when it wasn’t giving this error before?

Great @kasey.betts

I don’t have any idea, Basically this error occur we have use Kill process. In the back ground may be the file is processing I’m not sure about your process scenario.

So it worked a couple times but now it is back to throwing the same error even with the kill process activity

After Kill Process activity Use Delay activity set the Delay time as 00:00:05 and try it.

Can you share the workflow screenshot @kasey.betts
