    <h3>Details</h3>
    <p>This node generates the signed URL of a Google Cloud Store (GCS) object with action (READ/WRITE) and expiration time in mins .It returns the URL in the <code>msg.payload</code> field.

        At runtime, the value of msg.filename contains describes the file to read.  The format of this field is a GCS Url of the form <code>gs://[BUCKET]/[FILE]`</code> 
        Alternatively, we can specify the file to be read in the file name configuration property.  If both this property and a runtime value found in <code>msg.filename</code> are present, then the `msg.filename` name will be used.
    </p>
    The metadata associated with the file is returned in <code>msg.metadata</code>.
    </p>
