 That is it! 🎉 Once deployed, click the CloudFormation stack and go to **Outputs** tab, you can find the API Base URL from `APIBaseUrl`, the value should look like `http://xxxx.xxx.elb.amazonaws.com/api/v1`.
 
+### Troubleshooting
+
+If you encounter any issues, please check the [Troubleshooting Guide](./docs/Troubleshooting.md) for more details.

 ### SDK/API Usage
 
 All you need is the API Key and the API Base URL. If you didn't set up your own key, then the default API Key (`bedrock`) will be used.

+# Troubleshooting Guide
+
+This guide helps you troubleshoot common issues you might encounter when using the Bedrock Access Gateway.
+
+## Common Issues
+
+### 1. Parameter Store Access Error
+
+To see errors, first you need to access the CloudWatch Logs of the Lambda/Fargate instance.
+
+1. Go to the [CloudWatch Console](https://console.aws.amazon.com/cloudwatch/home?#logsV2:log-groups/)
+2. Search for `/aws/lambda/BedrockProxyAPI`
+3. Click on the `Log Stream` to see the error details
+
+```python
+botocore.exceptions.ClientError: An error occurred (ParameterNotFound) when calling the GetParameter operation: Parameter /BedrockProxyAPIKey not found.
+```
+
+This error occurs when the Lambda function cannot access the API key parameter in Parameter Store.
+
+**Possible solutions:**
+- Verify that you created the parameter in Parameter Store with the correct name
+- Check that the parameter name in the CloudFormation stack matches the one in Parameter Store
+- Ensure the Lambda function's IAM role has permission to access Parameter Store
+- If you didn't set up an API key, leave the `ApiKeyParam` field blank during deployment
+
+### 2. Model Access Issues
+
+If you receive an error about model access:
+
+```
+{"error": {"message": "User: arn:aws:iam::XXXX:role/XXX is not authorized to perform: bedrock:InvokeModel on resource: arn:aws:bedrock:REGION::foundation-model/XXX", "type": "auth_error", "code": 401}}
+```
+
+**Possible solutions:**
+- Ensure you have requested access to the model in Amazon Bedrock
+- Verify the Lambda/Fargate role has the necessary permissions to invoke Bedrock models
+- Check that you're using the correct model ID
+- Verify the model is available in your chosen region
+
+### 3. API Key Authentication Failures
+
+If you receive a 401 Unauthorized error:
+
+```
+{"detail": "Could not validate credentials"}
+```
+
+**Possible solutions:**
+- Verify you're using the correct API key in your requests
+- Check that the `Authorization` header is properly formatted (`Bearer YOUR-API-KEY`)
+- If using environment variables, ensure `OPENAI_API_KEY` is set correctly
+
+### 4. Cross-Region Access Issues
+
+If you're trying to access models in a different region:
+
+```
+{"error": {"message": "Region 'us-east-1' is not enabled for your account", "type": "invalid_request_error", "code": 400}}
+```
+
+**Possible solutions:**
+- Ensure the target region is enabled for your AWS account
+- Verify the model you're trying to access is available in that region
+- Check that your IAM roles have the necessary cross-region permissions
+
+### 5. Rate Limiting and Quotas
+
+If you're experiencing throttling or quota issues:
+
+```
+{"error": {"message": "Rate limit exceeded", "type": "rate_limit_error", "code": 429}}
+```
+
+**Possible solutions:**
+- Check your Bedrock service quotas in the AWS Console
+- Consider implementing retry logic in your application
+- Request a quota increase if needed
+
+## Getting Help
+
+If you're still experiencing issues:
+
+1. Check the CloudWatch Logs for detailed error messages
+2. Verify your AWS credentials and permissions
+3. Review the [Usage Guide](./Usage.md) for correct API usage
+4. Open a [GitHub issue](https://github.com/aws-samples/bedrock-access-gateway/issues/new?template=bug_report.md) with:
+   - Detailed error message
+   - Steps to reproduce
+   - Your deployment configuration (region, model, etc.)
+   - Any relevant CloudWatch logs
