Hi! First time poster, hope I'm making sense...
I have got a flow that uses the graph node with two different msg.topics at the input to graph two lines. I also have single graphs. All graph states are saved in textfiles and re-pushed into the graphs at startup. The single line graphs that are set up the same way, except they only receive one msg (not two topics), save without error - However. The graphs that have two lines in them give the following write error when writing the textfile on the chart state output.
"failed to write to file: Error [ERR_STREAM_WRITE_AFTER_END]: write after end"
It seems like the dual topics cause the node to do try writing a second time without opening the file correctly or something like that. I'm not a programmer so that's why I have to ask here if it's a bug or if it is somehting I'm doing wrong.
Strangely enough it seems to save the data correctly into the file even with this error(?)
To re-create:
connect the chart state output to a textfile and feed the graph with two streams with different topics
