Change_column_value with money or numbers


I am trying to update a single money column (but also an number column). I am struggling to find the correct syntax and the docs do not have enough information to troubleshoot.

mutation {
column_id: size_____max,
value: “{"WHAT-GOES-HERE?": "2.00"}”)

I have tried, value, float, number, integer, money … All result in the same error message

“error_code”: “ColumnValueException”,
“status_code”: 200,
“error_message”: “invalid value, please check our API documentation for the correct data structure for this column. Guide to Changing Column Values”,
“error_data”: {
“column_value”: “{"value"=>"2.00"}”,
“column_type”: “NumericColumn”

Thank you.
