Unable to retrieve validation definition name='XXX' id='XXX' from store (type=value_error) #10271

Describe the bug Cannot convert an ephemeral data context to a file context

To Reproduce

great_expectations.yml


# Welcome to Great Expectations! Always know what to expect from your data.
#
# Here you can define datasources, batch kwargs generators, integrations and
# more. This file is intended to be committed to your repo. For help with
# configuration please:
#   - Read our docs: https://docs.greatexpectations.io/docs/guides/connecting_to_your_data/connect_to_data_overview/#2-configure-your-datasource
#   - Join our slack channel: http://greatexpectations.io/slack

# config_version refers to the syntactic version of this config file, and is used in maintaining backwards compatibility
# It is auto-generated and usually does not need to be changed.
config_version: 4

# This config file supports variable substitution which enables: 1) keeping
# secrets out of source control & 2) environment-based configuration changes
# such as staging vs prod.
#
# When GX encounters substitution syntax (like `my_key: ${my_value}` or
# `my_key: $my_value`) in the great_expectations.yml file, it will attempt
# to replace the value of `my_key` with the value from an environment
# variable `my_value` or a corresponding key read from this config file,
# which is defined through the `config_variables_file_path`.
# Environment variables take precedence over variables defined here.
#
# Substitution values defined here can be a simple (non-nested) value,
# nested value such as a dictionary, or an environment variable (i.e. ${ENV_VAR})
#

Expected behavior Successfully export ephemeral context to file

Environment (please complete the following information):

Additional context Add any other context about the problem here.

adeola-ak commented 1 month ago

i think that behavior is usually done in the beginning of the file after fetching the context.

when i first fetch the context, and then use context.convert_to_file_context() to change it, i am not met with the error that you're facing

SiddhantSadangi commented 4 weeks ago

@adeola-ak This workflow used to run fine in gx<1.0

adeola-ak commented 4 weeks ago

i can look more into the cause of why it's not working similarly but are you unblocked now?

SiddhantSadangi commented 3 weeks ago

Hey @adeola-ak , Sorry, I have been a bit occupied.

I'll be unblocked if the workarounds suggested in #10270 work. I'll check and update both the threads.
