I have a VUscript which is replayed ok in VUGenerator.
When I put it in controller. Run for 5 minutes,
I got the error. But this error does not always happen.
Is there anyway to enable debug and how to view these debug information in controller ?
What exactly the error You are getting there ? Is it Internal Server Error ?? Or ...
You can view more information about the error in the Output window located on the top right quarter of the Controller. Click on it and click 'Details' to view it.
Re-run your test with extended logging enabled in the runtime setting for each script.
This will create a logfile for each vuser run in the \results\log directory.
Your script appears to have a web_reg_save param which has found no match in the response returned from your server.
Possibly your boundary conditions are not the same on every iteration? Or as the message states you could try increasing the param length in case the response is larger than 1024 characters?
Have a look at the Help for web_reg_save_param, you can set it to not throw an error even when an item is not found in the response. As you might not always expect a value to be returned for a particular parameter?
