Can confirm this bug.

Here's an image of the stack trace:

Every couple seconds, while scrolling on the suggestion list (wherever it is - I've seen it trying to fetch as a suggestion of html classes or as a suggestion of document autocomplete), it tries to fetch the suggestions from mongoose and this error pops.

Unfortunately this bug is extremely annoying I don't see another way other than disabling the extension for now.

Hey @glaubernespoli @MrRaymondVO,

Thank you for reporting the bug. I made this extension long ago and has not been maintained well for quite some time, I'm looking for devs who can help me maintain it. I'll try to figure out the cause of this bug and push a fix within this week, sorry for the inconvenience!

Question: Does this happen after approximately 10 seconds after you start scrolling through the autocomplete suggestions list? Then it might be because of this: https://github.com/roerohan/vscode-MongoSnippets-NodeJS/blob/91ca37137e3514e01620fc9df91a78dc74469dab/src/extension.ts#L52-L60

I will look into this, can u assign this to me?

[roerohan]

Sure @Mannan-Goyal

[roerohan]

@Mannan-Goyal any updates on this?

[thegiantbeast]

@roerohan indeed the issue is at line 55 providers.forEach((provider) => provider.dispose());. By commenting it out the issue goes away.

Can you give us some context for using setInterval? I'm not an extension dev but would like to help if I can.

[roerohan]

@thegiantbeast sorry for the extremely delayed response :sweat_smile:

Feel free to take a look at this extension. I've been working on other things so I haven't had time to maintain this. Which setInterval are you referring to, can you add a link for the same?
