AWS Polly InvalidS3RegionException
Understanding AWS Polly
AWS Polly is a service provided by Amazon Web Services (AWS) that turns text into lifelike speech. It allows developers to create applications that can talk, making it a powerful tool for creating voice-enabled applications. Polly supports a wide range of languages and voices, making it versatile for global applications.
Identifying the Symptom
When using AWS Polly, you might encounter the error InvalidS3RegionException. This error typically occurs when you attempt to use an S3 bucket in a region that is not valid for the operation you are trying to perform. The error message might look something like this:
{
"Error": {
"Code": "InvalidS3RegionException",
"Message": "The specified S3 region is not valid."
}
}
Understanding the Issue
The InvalidS3RegionException error indicates that there is a mismatch between the region of the S3 bucket you are using and the region expected by AWS Polly. AWS services are region-specific, and certain operations require resources to be in the same region.
Common Causes
- Incorrect region specified in your AWS SDK or CLI configuration.
- Using an S3 bucket in a region that AWS Polly does not support.
Steps to Fix the Issue
To resolve the InvalidS3RegionException, follow these steps:
Step 1: Verify S3 Bucket Region
Ensure that the S3 bucket is in a region supported by AWS Polly. You can check the region of your S3 bucket in the AWS Management Console:
- Navigate to the S3 Console.
- Select your bucket and check the region displayed in the bucket properties.
Step 2: Update Your Configuration
Ensure that your AWS SDK or CLI is configured to use the correct region. You can set the region in your AWS CLI configuration by running:
aws configure set region
Replace <your-region> with the correct region code (e.g., us-west-2).
Step 3: Modify Your Application Code
If you are using an SDK, ensure that the region is correctly specified in your code. For example, in Python using Boto3:
import boto3
polly_client = boto3.Session(
region_name='us-west-2'
).client('polly')
