Error: dynamodb the parameter cannot be converted to a numeric value

Answered by Rafal Wilinski
What's Causing This Error
This error is caused by passing strings, floating point numbers, null values, booleans, or complex data types when a decimal numeric value is expected.
If you pass a decimal value and still get the error, the value you pass might have exceeded the maximum limit of precision or scale allowed by DynamoDB.
Solution: Here's How To Resolve It
Make sure that the parameter being passed to DynamoDB is of the correct data type, such as a number or integer. If it is a string, convert it to a number. Also, properly handle data types and conversions before passing them to DynamoDB.
