[p-3]

i am getting

JavaScript error: file:///app/tns_modules/nativescript-purchase/transaction/transaction.js:27:28: JS ERROR TypeError: null is not an object (evaluating 'nativeValue.transactionState') *** JavaScript call stack:

after first successfully purchase has made on IOS.

The app crashes after this message.

any clue on this?

Hey @p-3 , sadly no idea what might be wrong and no idea how your workflow looks like. It will be best you debug your whole workflow and see what might be wrong.

thanks for fast reply..

nativeValue.transactionState seems to be NULL some times on

switch (nativeValue.transactionState)

in nativescript-purchase/transaction/transaction.ios.ts .. It seems to work if I add null check before but I would be more nice to know why it's null in some cases.

I did try to modify the transpiled js file to..

and everything seems to work for me, do you see any issues to have the NULL check before the switch case?

Hey @p-3 , thanks you for tracing this! I guess the null check is ok, but not sure how to treat such NULL state transaction and I can't find any reference in what situations the state can end up null. When you say everything works, in your workflow how do you treat such null state transactions? You just skip them?

The easiest way to get this error is by create a test flight subscription which is valid while the test flight version of app is active. and you get this when you upload new app version to TestFlight and remove the old one.

but I also have get this error with one time purchase products also but its also harder to get the error every time.
