Sry for the late response. I currently can't test your flow, but it looks like the webconnect node is crashing during requesting the available sessions. Did you maybe restart the flow to often and did not close the sessions correct? This also can happen if you request data to fast from the SB storage unit.
thank you for reply. It´s strange. I am using the nodes:
When i use only one of them, it runs stable. When using both the same time, node-red crashes after a view seconds.
I then moved to Node-Red on Linux (Redmatic). Now everthing is ok, its actually running since a couple of weeks without issues.
Maybe something wrong when using Node-red on Windows.........
Nothing changed on the flow, it´s the same.
Thank you for this information.
I'm using node-red with a Raspberry PI 3, I never tested it with Windows.
For me, too, exactly this error message occurred again and again:
[error] TypeError: Cannot read properties of undefined (reading 'name')
at Request.
I have two SMA inverters here in the house, one for the PV system, one for the battery. So there are two sma-webconnect-nodes running in my Node-Red, which are set to different IPs. When they are triggered by a repeating inject-interval at the same time, the above error message occurs. I solved the problem for me by using the same 15-second-inject-node for both sma-webconnect-nodes, but for one I added a 7-s-delay in between.
Just for the record: I have the exakt same problem as the other contributors to this issue.
My Flow did the job for over a year continously on
Raspberry PI ZERO W Node-Red v2.X Node.js V14.x (i guess)
After the update to Node-Red V3.x and NodeJS V16.x the trouble began. I will try the workaround from MakerMeik ...

Hello together, thanks to all of you for keeping on collecting your issues here. As you all seem to be using multiple instances of the node and the problem disappears after only using one or after using a delay to serialize the calls to the nodes, this raised a suspicion.
I've opened up a PR which might solve the issue. If anyone of you has JS knowledge, feel free to have a look and give feedback. :)
I am using node-red on Windows.
When trying to use sma webconnect node an set it to SB Storage, everthing went fine.
After a view minutes this error occurs:
TypeError: Cannot read properties of undefined (reading 'name') at Request. (C:\Users\xxx.node-red\node_modules\node-red-contrib-sma-webconnect\sma-webconnect.js:181:42)

This is my flow. It just reads from Storage Boy every 20 seconds and give the payload to a debug node:
