Rollbar throws errors about an non-existant out of memory error

[malua]

Hey,

we have a Capacitor app, which is a hybrid app. It opens a webview and shows a webapp. I wanted to add rollbar to the native ios project as well, to capture errors happening in the native wrapper.

This worked, but now Rollbar is throwing errors about an Out of memory error, which is not happening. The app does not have any issues. The log ouput is:

and crash collector (null)

Do you have any idea, what could trigger this oom error? also i can see the oomDetection "true" parameter in the rollbar config? can i somehow disable that - this would be workaround - altough i would rather capture actual oom errors, then disable it completely.

Hi @malua,

The actively maintained SDK for iOS is now rollbar-apple: https://github.com/rollbar/rollbar-apple

I recommend integrating that SDK which has many fixes and improvements, and if there is still an issue we can look at it there.

Hey @malua, You can find the documentation for the brand new Apple SDK here: https://docs.rollbar.com/docs/apple I'll close this ticket. Don't hesitate to open a new one in the Apple SDK repository whenever you run into any issues.

Ah man, how embarrasing. I am using the new SDK, I just posted into the wrong repo...

Thanks!
