<h3>Method Details</h3>
<div class="method">
    <code class="details" id="workerMessages">workerMessages(projectId, location, body=None, x__xgafv=None)</code>
  <pre>Send a worker_message to the service.

Args:
  projectId: string, The project to send the WorkerMessages to. (required)
  location: string, The [regional endpoint]
(https://cloud.google.com/dataflow/docs/concepts/regional-endpoints) that
contains the job. (required)
  body: object, The request body.
    The object takes the form of:

{ # A request for sending worker messages to the service.
    &quot;workerMessages&quot;: [ # The WorkerMessages to send.
      { # WorkerMessage provides information to the backend about a worker.
        &quot;workerMessageCode&quot;: { # A message code is used to report status and error messages to the service. # A worker message code.
            # The message codes are intended to be machine readable. The service will
            # take care of translating these into user understandable messages if
            # necessary.
            #
            # Example use cases:
            #   1. Worker processes reporting successful startup.
            #   2. Worker processes reporting specific errors (e.g. package staging
            #      failure).
          &quot;parameters&quot;: { # Parameters contains specific information about the code.
              #
              # This is a struct to allow parameters of different types.
              #
              # Examples:
              #  1. For a &quot;HARNESS_STARTED&quot; message parameters might provide the name
              #     of the worker and additional data like timing information.
              #  2. For a &quot;GCS_DOWNLOAD_ERROR&quot; parameters might contain fields listing
              #     the GCS objects being downloaded and fields containing errors.
              #
              # In general complex data structures should be avoided. If a worker
              # needs to send a specific and complicated data structure then please
              # consider defining a new proto and adding it to the data oneof in
              # WorkerMessageResponse.
              #
              # Conventions:
              #  Parameters should only be used for information that isn&#x27;t typically passed
              #  as a label.
              #  hostname and other worker identifiers should almost always be passed
              #  as labels since they will be included on most messages.
            &quot;a_key&quot;: &quot;&quot;, # Properties of the object.

          &quot;code&quot;: &quot;A String&quot;, # The code is a string intended for consumption by a machine that identifies
              # the type of message being sent.
              # Examples:
              #  1. &quot;HARNESS_STARTED&quot; might be used to indicate the worker harness has
              #      started.
              #  2. &quot;GCS_DOWNLOAD_ERROR&quot; might be used to indicate an error downloading
              #     a GCS file as part of the boot process of one of the worker containers.
              #
              # This is a string and not an enum to make it easy to add new codes without
              # waiting for an API change.

            # Due to this asynchrony, messages may arrive out of order (or missing), and it
            # is up to the consumer to interpret.
