该名称不能包含以下任何符号：'[, ], .'.'。 用于在 Azure 逻辑应用程序中撰写

Question

I have below JSON which I need to update inside a logic app

{
  "name": "SampleDoc",
  "type": "123",
  "properties": {
    "GP.Test": "M1",
    "MG.Test": "C1"
  }
}

I have used following setProperty syntax: -

@setProperty(variables('ResponseBody'),'properties', setProperty(variables('ResponseBody')['properties'], 'test','abc'),
setProperty(variables('ResponseBody')['properties'], 'GP.Test','M2'))

My desired JSON output should be

{
  "name": "SampleDoc",
  "type": "123",
  "properties": {
    "GP.Test": "M2",
    "MG.Test": "C1"
  }
}

But when I am running this, I am getting this error: -

InvalidTemplate. Unable to process template language expressions in action 'Compose' inputs at line '1' and column '2617': 'The provided property name 'GP.Test' has these invalid characters '.'. The name cannot contain any of the following symbols: '[, ], .'.'.

Could anyone suggest if we can handle '.' inside compose or any other way for achieving this?

Answer 1

Yes that is correct behavior that is occurring in the logic apps. The reason is that you have used the set property function to set the value of the GP.Test property. When working with the expressions in logic apps, the '.' operator is reserved operator and will be used to access sub properties etc of the expressions, functions etc. Hence you get the error. The solution to this is actually simple, you use the compose action directly without using the set property. Sample screenshot below.

Or if you want complex transformations, then using the liquid transformations through the integration account is the way to go
