Home Assistant Entity node sometimes errors

I'm using Node Red for to take a RESTful POST output and parse it out to various "edit entity nodes". I thought everything was working fine, but recently notices some "State must be defined" errors. They come and go as the inject post a REST query. Not sure why.

this a a small sample of the rest calls I'm making to bring the devices REST points into Node RED.

We need a little more info about your environment

Is this NR that is integrated with HA through HACS or is it a standalone version ?

What version of HACS and HASSio and NR are you running ?

Thanks Craig,
I think the REST device was simply taking too long to respond for NodeRed's liking. I staggered some of the REST calls and haven't noticed the error since.
