What's the best way to track *which* resource is missing?

I have an app that works completely without issue in QS, but gets the "ErrorCode.-2" randomly when I view it through an iFrame. Sometimes, the page will load completely, but then flickers, refreshes a few of the objects, and throws this error. I can't seem to get more detail from it.

This isn't a resource not found error. The error code is -2, not 2. We're getting the same thing.

It comes through as -2 because it's not found on the translation table.

Same issue here as well with Qlik Sense 2020 September Patch 6 and the code is -2

Hope someone finds why it is happening and possibly the way to fix the problem.

@woundine1 Are you going through a reverse proxy?

Yes, we are using Qlik Sense through reverse proxy

it's Enigma error

https://github.com/qlik-oss/enigma.js/blob/master/src/error-codes.js

I was able to get rid of this error when I removed the line from the extension app.variable.SetNumValue('MyVar',ValueOfMyVar)

this post also suggests that the source of the problems is app.variable

@Sir_Johanos

By any chance have you noticed any pattern when you see the error?

Does it occur after an specific selection?

Do you have any third party extensions, if so, if you remove them do you still see the error?

Have you seen if you have any obsolete objects in your app? for example qlik-show-hide-container is a deprecated object.

Kind Regards.

There is a workaround posted here.
However, I am having trouble applying the app.on("error"...) method to a Mashup with iframes. I cannot seem to get app.on to work on the iframes. I am applying it in the Mashup .js. Any suggestions?

I should add: I have found that using the iframe format generated using the "embed" function in the sheet itself throws the error far less frequently than using the format from the Single Configurator. But it still occurs.

Did anyone have any joy with fixing this? I thought that using a new extension object (SimpleFieldSelect) was causing it, but after removing that from my app I'm still getting the error. I get it whenever I open a new sheet within the app. However, older versions that have never had the extension don't get the error, so it's not merely having it installed that's causing the issue?

I'm kind of at a loss as to how to troubleshoot it, even. I've seen people mention adding lines of code, but I can't really imagine where or how?

Workaround:

The workaround is to manually catch the error and suppress it with app.on()

app.on('error', (er) => {YourErrorHandler})

That's all well and good, but I didn't create the extension, how / where would I add this?

Thanks for any help you can provide.
