Invalid JSON. A comma character ',' was expected in scope 'Object' Error

[Pedrogr90]

Hi people

I am trying to build a flow that creates a List with items

There is a column of type Choice , with a custom format defined in the Flow

I have a variable called "CustomFormatStatus" of type "String" defined like this:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "attributes": {
    "class": "=if(@currentField == 'Approved', 'sp-field-severity--good', if(@currentField == 'Not Selected', 'sp-field-severity--warning', if(@currentField == 'Not Approved', 'sp-field-severity--blocked', 'sp-field-severity--blocked'))) + ' ms-fontColor-neutralSecondary'"
  },
  "children": [
    {
      "elmType": "span",
      "style": {
        "display": "inline-block",
        "padding": "0 4px"
      },
      "attributes": {
        "iconName": "=if(@currentField == 'Done', 'CheckMark', if(@currentField == 'In progress', 'Forward', if(@currentField == 'In review', 'Error', if(@currentField == 'Has issues', 'Warning', 'ErrorBadge'))))"
      }
    },
    {
      "elmType": "span",
      "txtContent": "@currentField"
    }
  ]
}

Then below I have inserted this JSON in the HTTP Request like this:

And then when i run the flow , i get the following error:

I have tested the JSON in a test list and the formatting is applied correctly when the value changes, so i cannot really figure out what the problem is here.

Thank you in advance.

I'm not sure that it matters, but I noticed that in some places you used double quotes and in others you used single quotes.  Flow tends to be fairly touchy about the use of double quotes in JSON.  Change FieldTypeKind and Choices to single quotes and try again.

Solution:

Seems that if you have double quotes, then in order for the single quotes inside to be recognized as such, I had to put a \ just before the single quote
