Add ExpectationsStore with TupleAzureBlobStoreBackend to DataContext

Hi,

I am trying to add an ExpectationsStore with a TupleAzureBlobStoreBackend to DataContext, but I keep encountering errors related to saving the configuration to a YAML file:

ruamel.yaml.representer.RepresenterError: cannot represent an object:

I’m using the following versions:

  • great-expectations==1.1.0
  • ruamel.yaml==0.17.17

Steps to Reproduce the Error:

data_context = gx.get_context(project_root_dir="./expectations", mode="file")

store_config = {
    'class_name': 'ExpectationsStore',
    'store_backend': {
        'class_name': 'TupleAzureBlobStoreBackend',
        'container': 'container',
        'prefix': 'expectations',
        'connection_string': 'string',
    },
}

data_context.add_store(name="expectations_store", config=store_config)

Analysis:

I believe the issue stems from this part of the great_expectations.data_context.abstract_data_context module:

def _build_store_from_config(self, name: str, config: dict | StoreConfigTypedDict) -> Store:
    module_name = "great_expectations.data_context.store"
    # Set expectations_store.store_backend_id to the data_context_id from the project_config if
    # the expectations_store does not yet exist by:
    # adding the data_context_id from the project_config
    # to the store_config under the key manually_initialize_store_backend_id
    if (name == self.expectations_store_name) and config.get("store_backend"):
        config["store_backend"].update(
            {"manually_initialize_store_backend_id": self.variables.data_context_id}
        )

The data_context_id is a UUID, and when this UUID is added to the configuration, ruamel.yaml seems unable to parse it as a string, which causes the error.

Question:

Do you have any advice on how to resolve this error and correctly create the configuration?
