Lexical error: invalid char in json text

Hello experts,

we are getting a new error now when trying to use lots of channels:

17:18:00.803 WARNING: JSON error parsing _changes feed: lexical error: invalid char in json text.

We set the channels via the channels property of the pull replication, but it seems there is an error when too many channels are selected. When all channels are selected there are probably hundreds of them, and it seems that the URL query string that the CBL constructs for the sync is getting too long and that that causes problems.

Is there any setting to allow longer request URLs or is there some other easy way to fix this problem?

Thanks in advance,
