Plugins GetAllComments TypeError: Cannot read properties of undefined (reading 'RZ')


I got this error when open a pdf file after installing extended comments plugin. I’m using version 8.1.1.26.

This is what is logged in my server terminal:
Error [ERR_STREAM_PREMATURE_CLOSE]: Premature close

Please explain the error and help me fix it. Thank you.

Hello,
Please provide a screen recording showing the precise steps of issue reproduction as I wasn’t able to reproduce the issue doing the following: installed extended_comments plugin → created and opened pdf in the Editor.
Have you modified the plugin code or used the initial example_extended_comments plugin?
What is the browser that you are using?
Does it happen with a particular pdf? Please share the pdf file on which the issue was reproduced with us
