can query library list in Conan and can't auto generate Python file

[bac-ptit]

Hi everyone
I try to use Conan plugin in 3 device, 2 Windows and 1 Ubuntu, this has some problem when I use Conan

I could use it 3 days ago, but now, I can't use it

Thank you for your helps

Hi @bac-ptit

Thanks for your report.

It is difficult to see what is happening with a screenshot. Could you please copy and paste the text message from the window as text, not as an image?

It would also be good to:

• make sure that you update to the latest plugin version, also to latest Conan. Can you please report the Conan version?
• If you can share more reproduction steps, how to get that window, what steps do you follow until the message appears

Thanks!

Thanks for your reminder of my shortcomings.
I use CLion 2025.2(offical and early access 2025.3), I use CLion Windows, CLion WSL and CLion Fedora(Native)

about a few days ago, I use CLion via WSL, it works normally, but I delete conanfile.py and use Conan to generate Python file
it show this error

Hi @bac-ptit,

Thank you so much for reporting.
I have identified the issue, apparently it comes from some corrupted data in the file that stores the information about packages. I have just updated the file so if you update to the latest version the issue should dissapear. Could you please click on the update button of the plugin and check if that solves the issue. The button is this one:

[bac-ptit]

Oh, it works now. Thanks for helping me fix it. I thought it was down to my system and configuration before.

Thank you very much. @czoido
