Hello community, I have a msg.payload with multiple objects. I want to create a for loop in a function node to be able to run through all the objects one by one and append a property that is common to all the objects. I know I have to use the property path and it looks something llike this, payload…

You only needed to post the function, and tell us what is going in, which you have done already var activecalls = msg.call; var calls = 0; calls = activecalls.map(obj => callId); msg.call = calls; return msg.call; You should return a complete msg, so at the end return msg I suggest that unless y…

It would be best to show us an example of exactly what the data looks like, and show us exactly what you want the result to be.

[image] [image] I have a list with some objects (3 objects in this case 0,1, 2) and each object has a property location which itself is another object and has a property called ward and has a subproperty wardid. I want to extract the ward ids of all the objects (0,1,2) and compare them with ward i…

You can use Array.map() to convert the array list into a new array containing just the id values. Do the same with the other one and then you can compare them.

Read the docs page Working with Messages, if you have not already done so, and then have a play with the map() function as I suggested. If you can't get it to do what you need then ask again and show us what you have done so far.

[tempsnip] [function node] [Capture] [Error funcloc] Okay so if I replace object (msg.call = msg.call.list[object].functionalLocation.ward.wardId) to 0, it correctly reads the wardid and gives an output 3, however when I leave it as object, it gives me an error "TypeError: Cannot read property '…

In future please post code using the method in this link. How to share code or flow json You are overwriting msg.call the first time round the loop, which destroys what was there before, so the next time you execute that line there is no data there. Also you should not use for in for an array you…

Okay thank you, I will keep that in mind for next time. I read about the map method and looks like the ideal solution for my case. I am still figuring out a way to implement it though.

First understand the examples in the link I posted, then you just need to provide a function that returns the wardId.

That screenshot doesn't show location as being inside the array. You can expand the objects in the array by clicking on them
