Hi,
Just posting my final findings to this.
My issue was caused by the fact i was using Jackson 2.9.4 which logged: Cannot
writeAsString as adapter cannot be initialized.
When downgrading to 2.8.10 the writeAsString option worked perfectly,
outputting a valid Json string, rather than the Map toString().
This might also explain the NoTypeConversionAvailableException.
Maybe something to add to the docs ;)
Thanks for the help, cheers!
