util-dynamodb convertToAddr function does not identify objects with null prototype #1861
Description
Describe the bug
A clear and concise description of what the bug is.
This line does not identify objects created with a null prototype (i.e. Object.create(null)) and thus tries to decode a null-prototype object as a scalar value, eventually throwing the following error:
{
type: 'aws',
err: TypeError: Cannot convert object to primitive value
