For some reason it's getting confused when it has finished looking at the first line and moves on to the second.

For now I have reverted to 0.1.8 as that was the last known working version.

I had the same issue,
I found the pattern being that the unexpected char occurred after trying to deserialise a nil field.

Replacing the nils to 'none' before deserialising resulted in success.
But I had to then scan dictionaries to change 'none' to None.

I also had to have a script convert integers and floats for all childs
