Could you please provide clear steps to reproduce? Even better - could you please share the sample project?

[arulrajbt]

I would like to generate a spec file automatically using the 'Spec Generator' feature in 2.4 by passing the PageDump json file as an input.

But i'm getting Null pointer exception while calling the method generateSpecSections in SpecGenerator.

Please help me here.

It is not really clear how to reproduce this issue. Could you please share the pagedump and exact command that reproduces this issue?

[arulrajbt]

Attached the pagedump json file for reference.

page.zip

Command that throws Nullpointer exception
specGenerator.generateSpecSections(result)

[arulrajbt]

Please let me know if you need any other details

[ishubin]

Thanks for the sample file! I did manage to reproduce. Now all I need is to find some time and fix it.

[arulrajbt]

Thank you ishubin.

May i know the issue behind this please.

I have pushed a fix in the master branch. Tomorrow will try to make a minor release once I fix another issue.
I couldn't reproduce this issue with my own simplified page dump. But in your example it was failing on these two elements fleethome-ourapproach-container and fleethome-ourapproach-container-img.
Maybe the reason is that they are located off-screen as fleethome-ourapproach-container was located with -8 left position, but I am not sure
