describeProjectVersions method

Future<DescribeProjectVersionsResponse> describeProjectVersions({ required String projectArn, int? maxResults, String? nextToken, List<String>? versionNames, })

Lists and describes the versions of an Amazon Rekognition project. You can specify up to 10 model or adapter versions in ProjectVersionArns. If you don't specify a value, descriptions for all model/adapter versions in the project are returned.

This operation requires permissions to perform the rekognition:DescribeProjectVersions action.

May throw AccessDeniedException. May throw InternalServerError. May throw InvalidPaginationTokenException. May throw InvalidParameterException. May throw ProvisionedThroughputExceededException. May throw ResourceNotFoundException. May throw ThrottlingException.

Parameter projectArn : The Amazon Resource Name (ARN) of the project that contains the model/adapter you want to describe.

Parameter maxResults : The maximum number of results to return per paginated call. The largest value you can specify is 100. If you specify a value greater than 100, a ValidationException error occurs. The default value is 100.

Parameter nextToken : If the previous response was incomplete (because there is more results to retrieve), Amazon Rekognition returns a pagination token in the response. You can use this pagination token to retrieve the next set of results.

Parameter versionNames : A list of model or project version names that you want to describe. You can add up to 10 model or project version names to the list. If you don't specify a value, all project version descriptions are returned. A version name is part of a project version ARN. For example, my-model.2020-01-21T09.10.15 is the version name in the following ARN. arn:aws:rekognition:us-east-1:123456789012:project/getting-started/version/my-model.2020-01-21T09.10.15/1234567890123.
