Cannot generate test steps when starting recorder

When I try to start the recorder, it doesn’t work. I tried on few differents projets and it always says : Cannot generate test steps.

Here’s the error log :

So the null exception tells me that something with your object paths are not correct. Please check all paths are correct. A possible cause would be that the test objects of the test case have been removed or moved to another location.

It’s when I start the recorder. Tests cases are running fine. I tried starting the recorder on another project I have not modified and it doesn’t work either.

What version you using?

Katalon Studio 6.2 32 bits.

Hi @Nilau,

This issue occurs when KS tried to load the steps of the opened test case. We will update the fix of this issue in v6.3.0 release.

Thanks

Hi @Nilau,

Please update to v6.3.2 and please let us know if this bug still occurs.

Thanks

It fixed itself while ago.
