JSON query text error Monday.com api

Hi

I require help with an error I am receiving when querying the Monday.com api, I have tried multiple versions but just can't seem to resolve

I have 2 versions of the query and both are returning the same error at the JSON step

Version 1

let
Key = MondayKey,
Board = id_board,
Group = id_group1,
Source = Web.Contents(MondayBaseURL,
[
RelativePath="v2",
Headers=[
#"Method"="POST",
#"Content-Type"="application/json",
#"Authorization"= Key,
#"API-Version" = "2023-10"
],
Content=Text.ToBinary("{""query"": ""{ boards (ids: " & Board & ") {groups (ids: " & Group & " ) {items_page (limit:500) { cursor items { id name column_values { column{title} text}}}}}}""}")
]
),

#"JSON" = Json.Document(Source,65001),

Version 2

let
Key = MondayKey,
Board = id_board,
Group = id_group1,
Source = Web.Contents(MondayBaseURL,
[
RelativePath="v2",
Headers=[
#"Method"="POST",
#"Content-Type"="application/json",
#"Authorization"= Key,
#"API-Version" = "2023-10"
],
Content = Json.FromValue([query= "query { boards (ids: " & Board & ") {groups (ids: " & Group & " ) { items_page (limit:500) { cursor items { id name column_values { column{title} text}}}}}"])
]
),

#"JSON" = Json.Document(Source,65001),

The error is specific to the groups parameters and states it is expecting a text value. The boards parameter is also a text value and this resolves fine

All the parameters I reference in the query are text values

Any help or guidance would be appreciated

Thanks
