AWS Transcribe client does not provide an export named 'transcribeClient' - node.js

Question

I'm trying to integrate AWS Transcribe in my Node.JS application. AWS S3 and Polly works fine, but AWS Transcribe does not. I'm using the example code of AWS.
When I want to start a transcribe job by the AWS example code I receive the following error: The requested module './libs/transcribeClient.js' does not provide an export named 'transcribeClient'
That was also the only file where I received the error that required is not defined. I wonder why it only happens with AWS transcribe but not with the other services as well? I'm also able to start a transcribe job via the AWS CLI.
That AWS Transcribe code does not work - transcribeClient.js:
const AWS_BUCKET_NAME="X"
const AWS_REGION="eu-central-1"
const AWS_ACCESS_KEY="XXX"
const AWS_SECRET_KEY="XXX"
// snippet-start:[transcribe.JavaScript.createclientv3]
const { TranscribeClient } = require('#aws-sdk/client-transcribe');
// Create anAmazon EC2 service client object.
const transcribeClient = new TranscribeClient({ AWS_REGION, AWS_ACCESS_KEY, AWS_SECRET_KEY });
module.exports = { transcribeClient };
That AWS Polly code works - pollyClient.js:
const AWS_BUCKET_NAME="X"
const AWS_REGION="eu-central-1"
const AWS_ACCESS_KEY="XXX"
const AWS_SECRET_KEY="XXX"
// snippet-start:[polly.JavaScript.createclientv3]
const { PollyClient } =require( "#aws-sdk/client-polly");
// Create an Amazon S3 service client object.
const pollyClient = new PollyClient({ AWS_REGION, AWS_ACCESS_KEY, AWS_SECRET_KEY});
module.exports = { pollyClient };
I'm looking forward to reading from you! Thanks!

I solved it. Now it's working with my Node.js 12 environment.
package.json
I changed "type": "modules" to "type": "commonjs".
transcribeClient.js needs to look like this:
Here I changed export to module.exports.
const { TranscribeClient } = require("#aws-sdk/client-transcribe");
const transcribeClient = new TranscribeClient({ AWS_REGION, AWS_ACCESS_KEY, AWS_SECRET_KEY});
module.exports = { transcribeClient };
transcribe_create_job.js needs to look like this:
Here I changed the import statement to require.
const { StartTranscriptionJobCommand } = require("#aws-sdk/client-transcribe");
const { transcribeClient } = require("./libs/transcribeClient.js")
// Set the parameters
const params = {
TranscriptionJobName: "test123",
LanguageCode: "en-GB", // For example, 'en-US'
MediaFormat: "webm", // For example, 'wav'
Media: {
MediaFileUri: "https://x.s3.eu-central-1.amazonaws.com/dlpasiddi.webm",
},
};
const run = async () => {
try {
const data = await transcribeClient.send(
new StartTranscriptionJobCommand(params)
);
console.log("Success - put", data);
return data; // For unit tests.
} catch (err) {
console.log("Error", err);
}
};
run();
