Just upgrading a project to use v1.0.4 and seeing a problem when creating a table. I have a function that creates a table:

createResourceTable(removalPolicy: RemovalPolicy) {
  return new sst.Table(this, 'resourceTable', {
    fields: {
      datasetId: 'string',
      resourceId: 'string',
      ttl: 'number',
    },
    primaryIndex: { partitionKey: 'datasetId', sortKey: 'resourceId' },
    cdk: {
      table: {
        pointInTimeRecovery: true,
        billingMode: dynamodb.BillingMode.PAY_PER_REQUEST,
        timeToLiveAttribute: 'ttl',
        removalPolicy,
      },
    },
  });
}

but when it’s called SST is failing with:

TypeError: Cannot read property 'toUpperCase' of undefined
    at Table.buildAttribute (/Users/rosscoundon/Documents/GitHub/omw-pso-be/node_modules/@serverless-stack/resources/src/Table.ts:657:22)
    at Table.createTable (/Users/rosscoundon/Documents/GitHub/omw-pso-be/node_modules/@serverless-stack/resources/src/Table.ts:574:20)
    at new Table (/Users/rosscoundon/Documents/GitHub/omw-pso-be/node_modules/@serverless-stack/resources/src/Table.ts:278:10)
    at OmwPsoStack.createResourceTable (/Users/rosscoundon/Documents/GitHub/omw-pso-be/stacks/OmwPsoStack.ts:90:12)
    at new OmwPsoStack (/Users/rosscoundon/Documents/GitHub/omw-pso-be/stacks/OmwPsoStack.ts:360:32)

This points to the buildAttribute method:

private buildAttribute(
    fields: { [key: string]: TableFieldType },
    name: string
  ): dynamodb.Attribute {
    return {
      name,
      type: dynamodb.AttributeType[
        fields[name].toUpperCase() as keyof typeof dynamodb.AttributeType
      ],
    };
  }

I can’t really see how

fields[name]

is ending up

undefined

Any thoughts?

I ran across this issue as well after upgrading a project to SST 1.x. I had defined my PK/SK in the

fields

, but did not define the

ttl

attribute. Looks like you're having the same issue

That’s right, the thing that threw me was that the error was referencing the wrong place

Yeah, it was super confusing. I arrived at the same solution you did, but it was merely a guess

it’s nice to have company 🙂
