What's Causing This Error
This error occurs when the AWS SDK is unable to locate or validate the credentials from environment variables, the AWS credentials file, or the IAM instance profile. Mostly, this happens when the AWS credentials file or environment variables are not configured correctly or when the IAM role associated with the instance profile does not have the necessary permissions to access the DynamoDB table.
Solution: Here's How To Resolve It
There are several things you need to verify in order to fix this issue:
- Verify that your AWS credentials file is correctly configured with a valid access key and secret key.
- If you are using an EC2 instance, ensure that the instance has an IAM role with the necessary permissions.
- If you are running DynamoDB locally, ensure it is correctly running and that the AWS SDK version is compatible with the local DynamoDB version.
If non of the above methods works, you might have to pass the credentials explicitly to the DynamoDB client like below:
import boto3 dynamodb = boto3.client('dynamodb', region_name='us-west-2', aws_access_key_id='your_access_key', aws_secret_access_key='your_secret_key')
