Hi all I m having some issues with inputting `dict` type par

Question

Hi all I m having some issues with inputting `dict` type parameters in the Prefect UI and was wondering if anyone has come across the same I have a flow parameter `snowflake load config overrides` specified with a default value of `None` and type hint of `dict` ```snowflake load config overrides dict = None``` When I attempt to input a dictionary parameter in the UI the flow fails with the error ```prefect exceptions ParameterTypeError Flow run received invalid parameters snowflake load config overrides value is not a valid dict``` It appears if I inspect the parameter it is being interpreted as a string not as a Python dictionary ``` snowflake load config overrides s3 stage name S3 STAGE s3 prefix ``` Any insights Might this be a bug with the parameter validation logic

UI is just giving me a free text entry box it doesn t seem to know that this is meant to be `dict` datatype

Upon further inspection it appears my dictionary is considered invalid because it contains newlines and trailing commas so the parameter validation logic is coercing it to a string It is technically a valid dictionary but copy pasted into the UI it has issues
