How to add properties to a localVariable?

Posted on by TerryShowman

Hi, OnSelect of a Button I have the next code

UpdateContext({locDocument:MyPowerAutomateFlow.Run()})

that code creates a context variable called locDocument it returns some properties from the flow like these

{
"name":"foo",
"id":"12234",
"base64":"SG9sYU11bmQ="
}

so I am able to use in my app like locDocument .base64 or locDocument .id and so on. but I need to add more properties to that object (locDocument )

{
"name":"foo",
"id":"12234",
"base64":"SG9sYU11bmQ=",
"extra1":1,
"extra2":"string"
}

those extra properties are not handle by the MS Flow.

What can I do? thanks

What do you mean those properties are not handled by MS Flow? Are you referring to the issue with Respond to Power Apps trying to return a number? Or just that the other properties aren't available in Flow?

You can't add more properties to the existing Context variable. But you can create a new one that contains those properties and additional ones.

@JesusPrim @If you are looking to add columns to locDocument, you can use AddColumns(please check the syntax).

If you are looking for your Flow's return value should contain these extra columns, then you need to adjust the flow . So that in return it will provide you those extra columns.

@Pstork1 @Abhilash_Swain Hi thanks for reply. The flow just return 2 properties and thats it. it wont return more properties because aren't available in the MSFlow.
I've done something like this, it works but i think I'm doing the things wrong.
UpdateContext({locDocument:{ response:MyPowerAutomateFlow.Run(), extracontent:{extra1:1,extra2:"foo"} } });

Hi @JesusPrim
There is no easy way to add within Powerapps. We can do some splitting the response into the collection (A more tedious process), Add columns to add more properties, and to JSON.

The best approach is to send to another Power automate (It's easier in Power Automate). Which combines or add more properties. Get response as full JSON back.

Unless you want to create a separate Context Variable that is the best way to add additional values to locDocument.
