IAM actions are on the form service:action. In your example however, you have a space after the colon, making this into an object per the YAML specification. If converting your YAML to JSON, you would see that it has become:

"action": [{"dynamodb": "UpdateItem"}, {"dynamodb": "PutItem"}]

instead of

"action": ["dynamodb:UpdateItem", "dynamodb:PutItem"]

Removing the space should do the trick.

Action:
  - dynamodb:UpdateItem
  - dynamodb:PutItem

Sometimes it's also wise to quote strings containing special characters in YAML.
