Fatal Error in the PHPStorm

[lujewwy]

Hello! Recently I've started to receive a notification from my PHPStorm 2020.3.3 IDE regarding the exception in the plugin 'PHP RegExp Support (0.9.6)'. Here's the stacktrace from there:

Error during processing of: Type.php

1. Which PHPStorm version do you use?
2. What is the mentioned Type.php file? Is it a file from an opensource framework, or just a your private file (i.e. is it possible to see its source)?

[lujewwy]

1. PHPStorm 2020.3.3 (Build #PS-203.7717.64, built on March 16, 2021)
2. This file is from an opensource framework that can be found here: https://github.com/phan/phan.git and the path to the file there is src/Phan/Language/Type.php

[dryabov]

I've just released v.0.9.7, the issue should be fixed there.

Thank you for the quick reaction! For now it seems like it works without any errors.
