Error: DynamoDB Local Cannot Create Preexisting Table

Answered by Rafal Wilinski
What's Causing This Error
DynamoDB Local does not allow you to create more than one table with the same name. Because of that, you may encounter this error if it is needed to create a table with the same name as an existing table in the local DynamoDB environment. So, such an attempt will be responded to with a "Cannot Create Preexisting Table" error message.
Solution: Here's How To Resolve It
In this case, ensure that your table names are unique when it comes to creating new tables. If you wish to create a table with a name similar to an existing table, you can first use the DeleteTable method to delete the existing table.
It is always better to verify that the table you are attempting to create has a correct name and a primary key ahead of time and ensure that the table does not already exist in the local environment.
