InvalidParameterException: Request has invalid parameters when using startDocumentAnalysis

**Description**
I'm encountering an InvalidParameterException: Request has invalid parameters error when attempting to use the startDocumentAnalysis method with AWS Textract in a Node.js application. The error occurs despite ensuring that all parameters are correctly specified.

**Environment**

- Node.js Version: 18.20.3
- AWS SDK Version: ^2.1548.0
- AWS Region: ap-south-1

**Here's the code I'm using**

```
public async startAnalyiseDocument(key: string) {
try {
const response = await this.textreact
.startDocumentAnalysis({
DocumentLocation: {
S3Object: {
Bucket: env.AWS_BUCKET_NAME as string,
Name: key as string,
},
},
FeatureTypes: [
"TABLES", "FORMS", "SIGNATURES"
],
NotificationChannel:{
RoleArn:env.AWS_ROLE_ARN as string,
SNSTopicArn: env.AWS_SNS_TOPIC_ARN as string,
},
})
.promise();
console.log('ERROR:',response.$response.error)
return response;
} catch (error) {
console.log("AWS_TXT:", error);
throw new Error(error);
}
}
```

**Additional Information**

- The `RoleArn` and `SNSTopicArn` are correctly specified and the IAM role has the necessary permissions.
- Before implementing `NotificationChannel` it was working fine.

The relevant entry point is the startDocumentAnalysis call shown in the issue, especially the added NotificationChannel block. Start by checking the AWS SDK request parameters and the supplied role and topic values against the documented API requirements. Done means reproducing the request without InvalidParameterException and documenting the accepted configuration.
