I have some code in my serverless.yml like this currently.
resources:
Resources:
uploadBucket:
Type: AWS::S3::Bucket
Properties:
BucketName: ${self:service}-${self:custom.stage}-uploads
visitsTable:
Type: AWS::DynamoDB::Table
Properties:
TableName: ${self:custom.visitsTable}
AttributeDefinitions:
- AttributeName: userId
AttributeType: S
- AttributeName: visitId
AttributeType: S
- AttributeName: comments
AttributeType: S
- AttributeName: attachments
AttributeType: S
- AttributeName: ph
AttributeType: N
- AttributeName: ch
AttributeType: N
KeySchema:
- AttributeName: userId
KeyType: HASH
- AttributeName: visitId
KeyType: HASH
ProvisionedThroughput:
ReadCapacityUnits: 5
WriteCapacityUnits: 5
My goal is to create a table with primary key userId, sort key visitId and have fields for comments, attachments, ph & ch. When I try to sls deploy I get the following error.
Serverless Error ---------------------------------------
An error occurred: visitsTable - Property AttributeDefinitions is inconsistent with the KeySchema of the table and the secondary indexes.
What am I doing wrong here?
Edit: Another attempt I tried

Optionally, you can provide a sort key attribute and use a comparison operator to refine the search results. For more information on how to use Query , such as the request syntax, response parameters, and additional examples, see Query in the Amazon DynamoDB API Reference.
The sort key of an item is also known as its range attribute. The term range attribute derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value. Each primary key attribute must be a scalar (meaning that it can hold only a single value).
DynamoDB doesn't allow to add a sort key for an already existing table. Your only option is to create a new table with redefined key attributes and then copy the data from the existing table to the newly created table.
To give your application a choice of sort keys, you can create one or more local secondary indexes on an Amazon DynamoDB table and issue Query or Scan requests against these indexes.
AWS DynamoDb is a NO-SQL type database and no need to define all the keys during the Table creation. Also from the AWS documentation it's clear that in Attribute Definition you have to specify the Key schema and indexes.
An array of attributes that describe the key schema for the table and indexes.
