Subject: [PATCH] Fix PHP ^7.4 Notice:  Trying to access array offset on value
 of type null (#217)

It seems that under PHP ^7.4 this check is throwing an notice when trying to run a query without using primary/composite key as filter attributes (so when trying to run a DynamoDB scan). This fix checks if the key is set and uses null otherwise.
