@baris is correct, it is an error thrown by express because the large post is larger than the system default.
See http://expressjs.com/en/resources/middleware/body-parser.html#bodyparserjsonoptions
In NodeBB, we assume the default provided by body-parser, which is 100kb
If you want to support longer posts, update this value by adding this to your config.json
{
...
"bodyParser": {
"json": {
"limit": "1mb"
}
}
I take no responsibility for whether these values actually work, but I think they should 🙂
