Azure Data Factory Copy Data from CosmosDB to SQL DB Failing - UserErrorInvalidDataValue

I have a task to copy data from CosmosDB to a SQL DB
After about 30mins running it always fails with

Operation on target CosmosToSql failed: ErrorCode=UserErrorInvalidDataValue,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Column 'Imputed' contains an invalid value '0.10000000149011612'. Cannot convert '0.10000000149011612' to type 'Int64'.,Source=Microsoft.DataTransfer.Common,''Type=System.OverflowException,Message=Value was either too large or too small for an Int64.,Source=mscorlib,'

The Imputed field in Cosmos holds a floating point number- either 0 or a value between 0 and 1

the source is a SELECT c.Imputed FROM c

the sink is a SQL stored procedure. The data type of the Imputed column in the UDT form the table param
is [Imputed] DECIMAL .

Why/where is it trying to convert my float to an Int64?!
Nowhere is the variable defined as an integer.

and how to get around this?

    Hello @IanGlass-9566 ,
    Thanks for the ask and using the Microsoft Q&A platform .
    When you mentioned UDT , did you mean user defined table type ? if yes then at this time this scenario is not supported in ADF store proc , you can only pass native types .
    One work around which I can think is pass the columns as varchar and In the proc read the varchar ( I am assuming that it is a JSON ) .
    I request you to please upvote the ask here .
