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(?)
connect the chart state output to a textfile and feed the graph with two streams with different topics
