Dear All
Thanks for your attention. I’ve spent all this day trying to understand what is wrong with the buffer-array node. It is supposed that this node, receiving any payload in input, will output an array payload of a specified length.
Here following the proposed example flow.
In the above example, it is supposed to have a 2 item length array.
Everything is how expected in general.
At the first inject, because the “starting output when buffer filled” option is flagged, it waits for a second input
At the second inject it emits its first array payload
At the third inject
And so on.
At every inject the array payload will have always 2 items length.
If I start to make some little implementations, the situation suddenly changes for apparently no reason.
Let’s consider the following flow
To quick check, I’ve added the highlighted inject node.
Starting to inject timestamps I have the following
As you can see, the number of items inside the array grows at every injection.
I’ve tried many things to fix this but there is no way for me. I can state that in both cases (I have twin nodes that have different behaviours) I use the same payload as input but the output is different.
What do you suggest?
Here is the code
