Error using EXEC operator

[IgorShcherbakov]

For example, there is some kind of dynamic query (for simplicity, here is “SELECT 1 AS Result”):

The result of the check is an error:
"Error message": "1 validation error for GxConfig\nfluent_datasources -> assets -> 18 -> QueryAsset -> query\n query must start with 'SELECT' followed by a whitespace. (type=value_error)"
