Hi @euloge - Thank you for your question. There might be a syntax error in the configuration file: great_expectations.yml. In steps 1.3 and 1.4, when you copied the provided configurations to great_expectations.yml, did you pay attention to the indentation? The YAML file is indentation-sensitive. So that might be a possible reason for the error you got. If not, then you could share the yml file with me. I’m happy to look at it.
The file configuration was okay; that was the first thing I tried to check. Unfortunately, the lab is available only for 02 hours. If I have the same error, I will start a new lab and update the configuration file.
Thank you @euloge for sharing your file. The indentation in the file looks good. However some of the entries in each block need to be adjusted according to the instructions.
So for example, for expectation_store under store_backend:
class_name: TupleFilesystemStoreBackend (in your file) —> class_name: TupleS3StoreBackend (what it should be according to the instructions)
base_directory: expectations/ (in your file) —> prefix: expectations/ (what it should be according to the instructions)
Same remark for validations_store and checkpoint_store.
And finally for S3_Site, make sure the the block is exactly as:
