Creating an Expectation Suite With an Automated Profiler Great Expectation - python-3.x

Question

I am a newbie to great expectations and trying to set up but facing the below issue while creating an expectation Suite with an Automated Profiler.
C:\Users\user\great_expectations>great_expectations --v3-api suite new
Using v3 (Batch Request) API
How would you like to create your Expectation Suite?
1. Manually, without interacting with a sample batch of data (default)
2. Interactively, with a sample batch of data
3. Automatically, using a profiler
: 3
A batch of data is required to edit the suite - let's help you to specify it.

Answer 1

I had the same issue and, for me, the problem came from a badly configured data source. What I suggest you to do is to test your data source config and see how many datasets it found:
from ruamel import yaml
import great_expectations as ge
context = ge.get_context()
datasource_config = {...}
context.test_yaml_config(yaml.dump(datasource_config))
When running this, the test_yaml_config will output a report on how many assets it found.
If it didn't find any, then you'll run into the issue you're describing when you'll try to create a suite on your data.
