Send Web Request - Monday.com - Building JSON body with Monday's GraphQL

I am building a workflow that needs to have integration with Monday.com and I'm having trouble building the body of the web request step that I think is due to how Monday's GraphQL-based API translates into the JSON body in Workflow Manager.

Right now I'm able to create an item in Monday and update a single column value using the send request request step in WFM.

//ITEM CREATION { "query": "mutation CreateItem($board: ID!, $name: String!) { create_item(board_id: $board, item_name: $name) { id } }", "variables": { "board": "<board_id>", "name": Text(JobExtendedProperty($Job, 'portalsurvey', 'untitled_question_1')) } } //COLUMN UPDATE { "query": "mutation ChangeStatus($board: ID!, $item: ID!, $col: String!, $val: String!) { change_simple_column_value(board_id: $board, item_id: $item, column_id: $col, value: $val) { id } }", "variables": { "board": "<board_id>", "item": JobOutputValue ($Job, '<step_id>', '<output value from create item step>'), "col": "<column_id>", "val": "Working on it" } }

However, technically, I should be able to give a new item values or update multiple values per Monday.com's documentation.

//CREATING A NEW ITEM EXAMPLE mutation { create_item( board_id: 1234567890 group_id: "group_one" item_name: "new item" column_values: "{\"date\":\"2023-05-25\"}" ) { id } } //UPDATING MULTIPLE COLUMNS EXAMPLE mutation { change_multiple_column_values( item_id: 1234567890, board_id: 9876543210, column_values: "{\"status\":{\"index\":1},\"date4\":{\"date\":\"2021-01-01\"},\"person\":{\"personsAndTeams\":[{\"id\":9603417,\"kind\":\"person\"}]}}" ) { id } }

In Workflow Manager, I've tried the following:

1. Writing the query with values inline, such as:

"query": "mutation { create_item(board_id: <board_id>, item_name: \"@{Text(JobExtendedProperty($Job, 'portalsurvey', 'untitled_question_1'))}\", column_values: \"{\\\"<column_id>\\\":\\\"hello\\\"}\") { id } }"

2. Writing it with variables as I did in my working versions. I tried having the column values variables as JSON! and STRING!

{ "query": "mutation CreateItem($board: ID!, $name: String!, $col: JSON!) { create_item(board_id: $board, item_name: $name, column_values: $col) { id } }", "variables": { "board": "<board_id>", "name": "<item_name>", "col": "{\"<column_id>\":\"hello\"}" } }

Both of these are resulting in errors from WFM saying that 'Web request failed: Web request body is not valid JSON', 'Unable to Parse JSON', and 'Step failed with error: InvalidArguments'.

I'm fairly confident that I have the overall syntax correct because when I test the two above web requests in Postman, they work just fine, but it fails when it's in Workflow Manager.

Any troubleshooting suggestions or advice is much appreciated!
