Unable to find a region via the region provider chain

[sneiderV]

Hi, I'm interested in using textrack and I read the instructions mentioned in the main page of Amazon like those of this repository.

I am using the class: DemoPdfFromLocalPdf.java But I get the following error when run application:

com.amazonaws.SdkClientException: Unable to find a region via the region provider chain. Must provide an explicit region in the builder or setup environment to supply a region. at com.amazonaws.client.builder.AwsClientBuilder.setRegion(AwsClientBuilder.java:462) at com.amazonaws.client.builder.AwsClientBuilder.configureMutableProperties(AwsClientBuilder.java:424) at com.amazonaws.client.builder.AwsSyncClientBuilder.build(AwsSyncClientBuilder.java:46) at com.amazonaws.services.textract.AmazonTextractClientBuilder.defaultClient(AmazonTextractClientBuilder.java:45) at DemoPdfFromLocalPdf.extractText(DemoPdfFromLocalPdf.java:28) at DemoPdfFromLocalPdf.run(DemoPdfFromLocalPdf.java:73) at Demo.main(Demo.java:10)

I try to use in this class (DemoPdfFromLocalPdf.java) the method .withRegion to set it:

AmazonTextractClientBuilder client = AmazonTextractClientBuilder.standard().withRegion(Regions.US_EAST_1); but, show the same error.

finally, use the .isServiceSupported method to know in which Region the service was available, use all regions (21 Regions) but always throw me false in the response. Maybe the service is not hosted in any region, to make free use? System.out.println("isSupported: "+Region.getRegion(Regions.EU_CENTRAL_1).isServiceSupported(AmazonTextract.ENDPOINT_PREFIX));

any idea of this?

Thank you.

Do you have AWS CLI setup with default region? See link below for more details: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/setup-credentials.html

Hi , I have had the same problem too. Reading in this page about "Explicitly Specifying Credentials", I have tried to do the same in this class: DemoPdfFromLocalPdf.java

Firstly, I have created my "access_key_id" and "secret_key_id" following this.

Then, I have altered the class (DemoPdfFromLocalPdf.java) this way:

BasicAWSCredentials awsCreds = new BasicAWSCredentials("access_key_id", "secret_key_id");
AmazonTextract client = AmazonTextractClientBuilder
                                .standard()
                                .withCredentials(new AWSStaticCredentialsProvider(awsCreds))
                                .withRegion(Regions.US_EAST_1)
                                .build();

So far, it works for me!
