AWS dynamodb boto3 ResourceNotFoundException: An error occurred when calling the PutItem operation:

I'm new to AWS and DynamoDB, I'm trying to send data to a table.

I'm running this code:

import boto3

db = boto3.resource('dynamodb')
table = db.Table('Whales')

table.put_item(
    Item={
        "id": "1573138502",
        "transaction_type": "transfer",
    })

and I get this error:

Traceback (most recent call last):
  File "/Users/---/Desktop/---/---/test.py", line 6, in <module>
    table.put_item(
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/boto3/resources/factory.py", line 520, in do_action

    raise error_class(parsed_response, operation_name)
botocore.errorfactory.ResourceNotFoundException: An error occurred (ResourceNotFoundException) when calling the PutItem operation: Requested resource not found

I installed boto3, I identified myself using the aws cli, I also tried running the code from AWS Cloud9 EC2 instead, but it didn't work, same error.

I have not been able to send anything to the db from Python, I don't understand where the problem comes from or what's causing it.

Solution

  • You most likely have the DynamoDB Table in a different region than the one specified in your ~/.aws/config.

    Try cat ~/.aws/config and check what region you are connecting with. ie us-east-1.

    Verify that your DynamoDB is in the same region using the AWS Console or other CLI tools.

    From what I see, your code should not by syntactically wrong.
