I use open-weather a lot and just recently it is throwing weird errors at me.

As _we_ are going into winter, (ok, Autumn) it is raining more and more.

For now I am doing a series of weather gets from midnight to mid day to see how much rain has fallen.  
(Each hour, there about)

This shows the error (kind of) and the time. `02:00` and `The API call returned invalid JSON`

This is a list of attempts to see what is the problem:  
Yeah, not perfect as the `objects` aren't expandable, but let's accept that and move on - for now.

 ![Screenshot from 2024-04-10 06-42-30](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/6/f/6f7cbd9eee4a52603aa9c4cf98b71536154d0bd2.png)

You can see the _replies_ (messages) at `00:00`, `01:00`, `03:00`, `04:00`, `05:00` and `06:00`.  
The big red arrow points to where the error causing `02:00` message should have been.

There isn't/wasn't a message sent.

Looking at the flow.  
Yes, it is a bit full on.  
Let's concentrate on the red area/s.

the `open-weather` node. The output goes to a `link` node. That then goes down and is _logged_.  
A `timestamp` is created for WHEN it happened, a `template` node _formats_ the message and a `queue` node queues them, and finally a `debug` shows them.

I need to do work on getting it to expand the `objects`, but I'm not sure that is the problem.

As you can see nothing was output at `02:00`, so that has me confused to the `invalid JSON` message.  
If anything was output, it would/should have been logged - yes?

This is happening with annoying regularity recently. But not always at 02:00 - or I am not 100% sure.  
The last few times - where were the start of this trend - I didn't really check that.  
I saw the error message and kind of grumbled.  
But now it seems to have established itself as a daily thing.

Just to mention - though I don't think it is relevant: Sunday morning (today is Wednesday) we went from SUMMER TIME back to NORMAL TIME.  
But as just said, that was now `5` days ago.  
Which is why I didn't worry the first couple of times - stupidly.

Any ideas?

Thanks in advance.

That's great news, thanks Andrew, it must mean that summer is now heading our way here in the UK 😉

Is/Are there restrictions on what you can send into the node?

I have _test_ buttons and I can press them _until the cows come home_ and it works.  
It fails daily between 00:00 and 12:00  
Ok, that is a 6 hour gap in which I can look, but.... 😉

I did notice that somehow the node wasn't getting a simple incoming message.  
Say like `go`.  
But more like: `02:00 2024-04-10 1` Alas I wiped the debug list/output.

I have (today) put in a `change` node just before the input to the node and made it a `go` message.  
I'll see what happens tonight.

More information after more testing.

 ![Screenshot from 2024-04-10 19-41-35](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/4/c/4ca2b5c54a79b904d79a02b08f2c49e7054b3d2a.png)

The code on the screen is _called_ with the `link call`, `link in` and `link out` nodes.

I invoked the code from the higher level and noticed that I am getting this error.

Strange.

The node is set to `return to calling node`.

So, is this part of the problem?

</div>

Somewhere down your flow (between the LINK-IN and the LINK-OUT return) a node is either discarding the important "return data" (i.e. data that tells the return node which LINK-CALL to send the msg back to) OR you have a naughty node that is generating NEW `msg`s (the effect is the same).

Add debug nodes along the flow (set to show FULL message) - you will see at the beginning of the flow there is some extra data that indicates which LINK-CALL to return to, then further along, it will be gone.

common causes are misbehaving nodes and functions that generate new messages (instead of returning the original `msg`)

Ah!

That's an interesting spin on things.

Yes, I'll put my hand up now and say that is very possible to have happened.

ITMT, I've put it back to _simple_ `link-in/out` nodes. It isn't used by anyone else.  
I used the `call` node only to get some understanding on it's workings.

Seems that you found something I didn't think of and I will say that is the problem.

The last pictures shows the `COMPLETE RETURN MESSAGE` and that will probably have _wrong_ information compared to the inbound message.

THANKS!

(Although.......)

In the first few pictures, you see most of the messages seem to be getting through and _working_.

Just now and then one doesn't.

If it was that my code was corrupting the message:  
Why only certain ones?

Maybe if there was/wasn't rain something happened.

But for the sake of all: I will accept your reply.  
This was just an after thought I saw after marking that as the solution.
