HTTP errors POSTing to 8.11.2

[dmitri maziuk]

Hi all,

has anyone gone through the exercise of replacing Data Import Handler 
with scripts that POST JSON and if so, are your scripts still working OK 
with 8.11.2?

I got a few that work fine with 6.5 and 8.7 but are throwing 503s and 
occasional 400s all over the place with 8.11.2.

Solr isn't logging anything useful (at least not at INFO level) and I 
can't quite figure out what's up. I tried tweaking the scripts in all 
kinds of ways but that isn't helping. The same VM previously ran 6.5 
where these problems didn't exist. So I am inclined to blame 8.11.2 at 
this point.

Is there some new security settings I need to tweak to POST or 
something? Any other suggestions?

TIA
Dima
