Hi, I was exploring great\_expectations and trying the sample code listed in the tutorial, however I am seeing this error:  
add\_or\_update\_checkpoint() got an unexpected keyword argument ‘validator’  
Any pointers to it?

import great\_expectations as gx  
context = gx.get\_context()  
validator = context.sources.pandas\_default.read\_csv(  
“[https://raw.githubusercontent.com/great-expectations/gx\_tutorials/main/data/yellow\_tripdata\_sample\_2019-01.csv](https://raw.githubusercontent.com/great-expectations/gx_tutorials/main/data/yellow_tripdata_sample_2019-01.csv)”  
)  
validator.expect\_column\_values\_to\_not\_be\_null(“pickup\_datetime”)  
validator.expect\_column\_values\_to\_be\_between(“passenger\_count”, auto=True)  
validator.save\_expectation\_suite()  
#checkpoint = context.add\_or\_update\_checkpoint(name=“my\_quickstart\_checkpoint”,validator=validator)  
checkpoint = context.add\_or\_update\_checkpoint(name=“my\_taxi\_validator\_checkpoint”, validations=validator)  
checkpoint\_result = checkpoint.run()

Hi @bn45780 that same code is running fine on my end. Which GX version are you using? Also, what does your folder structure for GX look like?

It is 0.16.13. Do I need to update it to 0.17.15 ?
