Some lottiefiles does not work

[guitar9]

I get error: java.lang.IllegalStateException
For example with this lottiefile: https://lottiefiles.com/5997-white-house?lang=de
I tried it with the example project and tried different lottiefiles. Some lottiefiles worked, some dont work and some crashes the app.

Failure loading resource: com.airbnb.lottie.parser.moshi.JsonEncodingException: Use JsonReader.setLenient(true) to accept malformed JSON at path $

I could not make none of the lottiefiles to work from QR code. The sample app kept crashing
