What would be the expression to focus on an array within an object?

[tparsons]

I'm new to expressions in Flow and could do with some help.

What would be the expression to see if the 'value' key in this object has any items in the array?

I tried `empty(body('List_records')['value'][0].length)` - and many more expressions - but i can't get it working.

{
"@odata.context": "https://unitedstates-002.azure-apim.net/.....",
"value": []
}

If you need to check if an array contains any values, you could use the Length expression within a Condition.

That works, thanks. I just kept putting the expression incorrectly.
