Hello,
I have implemented an existing flow to read out data from the Sunny Home Manager. A function buffer parser gives me an error message in the online status: "scale.match is not a funtion". Does anyone have any idea where the problem could be.
Thank you in advance.
Hi @Ben_F
without more specific information about your flow, its hard to say much about where the problem is.
The only information you've given us is the error message: "scale.match is not a funtion".
This tells us that somewhere in your flow, something is trying to call a function called match on a variable called scale - but for some reason that function doesn't exist.
That could be because scale is not of the right type. match is an function of String objects. So that suggests the code assumes scale is a String but for some reason it isn't one. It could be undefined or some other thing entirely.
That's about the limit of what we can say based on the information you've shared.
I assume you mean you are using the buffer parser node. Can you spare your flow and some sample data. Do not include the other non standard nodes - instead, use an inject node to simulate this sunny data.
Hi,
das ging ja flott. Angehangen mein Flow

As i dont have your data, I cannot tell you the issue.
Add a debug like this...
Ensure the debug is set for full msg...
then copy a few data transmissions like this...
and paste it into a reply by pressing the code button...
... then pasting the copied value in the middle of the backticks
Here it is.

That data works perfectly fine for me...
I suspect 1 of 2 things...
What node-js version are you using?
Also,
Can you add a catch node attached to msg
then copy the catch the error & copy paste the copy value when the error occurs...
In which palette I find the node-js?
hope that's so right.

In a terminal, type node -v
Also, in the palette, what version is buffer-parser?
That payload works for me - I suspect you are on NODE-JS version less than 12.
Buffer-parser is version 3.1.6
Can I only check the node-js version in the terminal?
Then I have to look for my password first an have to continue tomorrow. Wife calls me to bed. Both children are sick.
You can do it from an exec node to run node -v
I think you will find you are on an old version.
If you are running on a PI or Debian based linux system, you can upgrade node-red to latest and node-js at the same time...
Open a terminal then paste in the below...
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node14
full info here: Running on Raspberry Pi : Node-RED
I'll try tomorrow. Thank you in advance.
Hi Steve,
did the update and see that it works. Thank you very much.
