Hi @bkhawarABC,

Thank you for the report. Can you maybe share with us what are the keys and values that you are attaching as session callback parameters (when invoking addSessionCallbackParameter:value: of Adjust)? Are you making sure that all of them are NSStrings before passing them to the method?

Hi,

we have similar crash. We can't replicate the crash, but in dashboard there's a few crash related to this. On the comment from @uerceg we are using String everywhere. the crash report:

It mainly happens on iPad, but there are some crashes on iPhone as well.

Hi @ZurabiKobakhidze,

Those two should be not related. I believe that your crash is similar to this one. I am also noticing that you are using iOS SDK v4.38.1. Would it be possible for you to update your SDK to the latest version and let us know if you are seeing those crashes still happening?

[mattiacantalu]

Hi @uerceg,
tbh we found occurrences the same crash even in latest SDK 4.38.4, the version we have in production right now. Any idea about that?
Maybe it's better moving the discussion here #639 ?

[bkhawarABC]

@uerceg After investigation, I found that there might be a case in which one of the parameter is an Integer rather than a String. I'll make that change on my end to enforce a NSString for those cases. Hopefully, that resolves the issue.
