When using ExcelReader in a loop, an IllegalStateException occurs at random times.

Hello community!

I’m using v5.2.3 on Windows 10.

As the title says, when I read Excel with ExcelReader in a loop, sometimes an “IllegalStateException” error occurs and the process stops.

If I select the node in the failed state and click “Execute”, it ends normally.

What do you think is causing this?

*This error occurs when I open a workflow created in v4.7.3 in v5.2.3. It does not occur in v4.7.3.

*I extracted the v5.2.3 zip file, opened the same workspace and ran it, and got an error.

*The same problem occurs even if I drag and set a new ExcelReader.
