UNEXPECTED END OF JSON INPUT IN LINE 1

[Samuel Victor]

Good day fam ❤️

I came across a fatal error on two projects I have in DroidScript. All of a sudden, they were unable to run successfully and I haven't touched the code base in while.

I get the error "Unexpected end of JSON INPUT in line 1" when I check - it's completely unrelated to the error itself.

The code works fine, as it used to. Just this error that came up recently.

I feel like it's DroidScript itself rejecting these projects.

Any help would be highly appreciated 👍 ❤️

We need to narrow down which bit of code is causing it.  Please make a copy of your app and then cut out chunks of code until you have a very simple bit of code that still shows the problem, then post it here.

I can't exactly spot where the problem comes from two projects I haven't touched in a while. Each project code has about 1-2k lines of code. But the error points to line 1 and there's nothing related there. Here are pictures

The crypt object in DroidScript for encryption when called to encrypt returns a different cipher text from crypt.Encrypt("string");
I now later realized that crypt=app.CreateCrypt(without any parameters); when declared behaves exactly like this but sometimes decrypt successfully. I realized they recently added 'AES or ECB or PKCS5 padding as parameters optional' I decided to stick with AES and the problems I encountered stopped. It seems this was an update to the crypt object. I have fixed the problem successfully but can anyone explain why?

The cryipt object now uses "AES/GCM/NoPadding" because Google Play developer console keeps warning you if you continue using the old AES/ECB/PKCS5Padding as it is considered insecure these days.  So we updated the default method, but if you have previously encrypted content, you will need to pass the "AES/ECB/PKCS5Padding" option to decrypt that older stuff.

If you mix the two worlds, then you need to mark/record that the newer content uses the newer method.
