Setup node variables in function node on start

General
1

Hi folks,

My first question in 2022, and it is a noob level one. First time that I use the "On start" tabsheet in the function node...

All my code in the "On start" tabsheet is executed correctly, but when I add this:

node.workers = [];

And I use that node variable in my "On message" tabsheet:

node.workers.push(...);

Then I get "TypeError: Cannot read property 'push' of undefined" in my Debug sidebar.

I suppose it is something ridiculous, but can't see it. When I debug the code, the node variable is nicely available and I can use it here e.g. to show an initial node status.

Thanks!!!
Bart

Hmm, don't think it has anything to do with my startup tabsheet.

  1. For the first message that I inject, an element is added correctly to my array:

    image

  2. When I inject another message my array is undefined again:

    image

I am ready for the madhouse at the moment...

Use context not node to store values across different calls to the function

Not sure how I could have overlooked that ...
