Args:
  readGroupSetId: string, The ID of the read group set to be deleted. The caller must have WRITE
permissions to the dataset associated with this read group set. (required)

Returns:
  An object of the form:

    { # A generic empty message that you can re-use to avoid defining duplicated
      # empty messages in your APIs. A typical example is to use it as the request
      # or the response type of an API method. For instance:
      #
      #     service Foo {
      #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);

  x__xgafv: string, V1 error format.
    Allowed values

      2 - v2 error format

Returns:
  An object of the form:

    { # This resource represents a long-running operation that is the result of a
      # network API call.
    "metadata": { # An OperationMetadata object. This will always be returned with the Operation.
      "a_key": "", # Properties of the object. Contains field @type with type URL.
    },
    "error": { # The `Status` type defines a logical error model that is suitable for different # The error result of the operation in case of failure or cancellation.
        # programming environments, including REST APIs and RPC APIs. It is used by
        # [gRPC](https://github.com/grpc). The error model is designed to be:
        #
        # - Simple to use and understand for most users
        # - Flexible enough to meet unexpected needs
        #
        # # Overview
        #
        # The `Status` message contains three pieces of data: error code, error message,
        # and error details. The error code should be an enum value of
        # google.rpc.Code, but it may accept additional error codes if needed.  The
        # error message should be a developer-facing English message that helps
        # developers *understand* and *resolve* the error. If a localized user-facing
        # error message is needed, put the localized message in the error details or
        # localize it in the client. The optional error details may contain arbitrary
        # information about the error. There is a predefined set of error detail types
        # in the package `google.rpc` that can be used for common error conditions.
        #
        # # Language mapping
        #
        # The `Status` message is the logical representation of the error model, but it
        # is not necessarily the actual wire format. When the `Status` message is
        # exposed in different client libraries and different wire protocols, it can be
        # mapped differently. For example, it will likely be mapped to some exceptions
        # in Java, but more likely mapped to some error codes in C.
        #
        # # Other uses
        #
        # The error model and the `Status` message can be used in a variety of
        # environments, either with or without APIs, to provide a
        # consistent developer experience across different environments.
        #
        # Example uses of this error model include:
        #
        # - Partial errors. If a service needs to return partial errors to the client,
        #     it may embed the `Status` in the normal response to indicate the partial
        #     errors.
        #
        # - Workflow errors. A typical workflow has multiple steps. Each step may
        #     have a `Status` message for error reporting.
        #
        # - Batch operations. If a client uses batch request and batch response, the
        #     `Status` message should be used directly inside batch response, one for
        #     each error sub-response.
        #
        # - Asynchronous operations. If an API call embeds asynchronous operation
        #     results in its response, the status of those operations should be
        #     represented directly using the `Status` message.
        #
        # - Logging. If some API errors are stored in logs, the message `Status` could
        #     be used directly after any stripping needed for security/privacy reasons.
      "message": "A String", # A developer-facing error message, which should be in English. Any
          # user-facing error message should be localized and sent in the
          # google.rpc.Status.details field, or localized by the client.
      "code": 42, # The status code, which should be an enum value of google.rpc.Code.
      "details": [ # A list of messages that carry the error details.  There will be a
          # common set of message types for APIs to use.
        {
          "a_key": "", # Properties of the object. Contains field @type with type URL.
        },
      ],
    },
    "done": True or False, # If the value is `false`, it means the operation is still in progress.
        # If true, the operation is completed, and either `error` or `response` is
        # available.
    "response": { # If importing ReadGroupSets, an ImportReadGroupSetsResponse is returned. If importing Variants, an ImportVariantsResponse is returned. For pipelines and exports, an empty response is returned.
      "a_key": "", # Properties of the object. Contains field @type with type URL.
    },

  }

The caller must have WRITE permissions to the dataset.

## Notes on [BAM](https://samtools.github.io/hts-specs/SAMv1.pdf) import

- Tags will be converted to strings - tag types are not preserved
- Comments (`@CO`) in the input file header will not be preserved
- Original header order of references (`@SQ`) will not be preserved
- Any reverse stranded unmapped reads will be reverse complemented, and
their qualities (also the "BQ" and "OQ" tags, if any) will be reversed
- Unmapped reads will be stripped of positional information (reference name
and position)

search_next(previous_request, previous_response)
Retrieves the next page of results.

Args:
  previous_request: The request for the previous page. (required)
