How to modify dataflow runtimevalueprovider args while passing to pardo?

I'm encountering an issue while attempting to modify the arguments passed to a RuntimeValueProvider in an Apache Beam Dataflow pipeline. Here's a simplified version of my code:

import apache_beam as beamfrom apache_beam.io.textio import WriteToTextfrom apache_beam.options.pipeline_options import (GoogleCloudOptions,                                                  PipelineOptions)class DataflowFlags(PipelineOptions):  @classmethod  def _add_argparse_args(cls, parser):    parser.add_value_provider_argument("--output_path",        dest="output_path",        type=str,        default="./python_extract_output",    )    parser.add_argument("--project_id", dest="project_id", default="test"    )class ExtractPipelineRunner:  def __init__(      self,      output_path: str,  ):    self.output_path = output_path  def run(self, p: beam.Pipeline) -> None:    _ = (        p        | "Create" >> beam.Create(["hello", "world"])        | "WriteToText" >> WriteToText(self.output_path.get() +"test/")    )def main() -> None:  pipeline_options = PipelineOptions()  known_args = pipeline_options.view_as(DataflowFlags)  pipeline_options.view_as(GoogleCloudOptions).project = known_args.project_id  with beam.Pipeline(options=pipeline_options) as p:    extract_runner = ExtractPipelineRunner(known_args.output_path)    extract_runner.run(p)if __name__ == "__main__":  main()

I'm trying to modify the output_path by appending an extra value to it before passing it to WriteToText, but I encounter the following error:

apache_beam.error.RuntimeValueProviderError: RuntimeValueProvider(option: output_path, type: str, default_value: './python_extract_output').get() not called from a runtime context

How can I solve this issue? I want to be able to modify the RuntimeValueProvider arguments appropriately. Thank you for your help!

I want to dynamically trigger a Dataflow template every month and append the current month(i.e. in place of "test/") as a string to the output path. I've attempted to achieve this by using a StaticValueProvider, but it's not updating every month.
