Hi, when I run $ henry pulse I get the following error: AttributeError: module 'looker_sdk.rtl.serialize' has no attribute 'serialize40'

Here is the full tree:

I am having the following set up (run in python 3.7 environment):

`Python3.7_env) pko@pko-VirtualBox:~/Desktop$ pip list
Package Version

attrs 23.2.0
cattrs 1.1.2

typing_extensions 4.7.1

Also I am using .ini configuration file stored in the working folder.

Could somebody help with this error ?
Thanks!

Cheers!

Hello @rePetko
Which of the commands working for you?
Can you please share as much info for environment as possible to maybe replicate it, i.e.

• can you send again the pip list please
• can you share you .ini file (of course with creds or base_url hidden, just want to understand if i'm doing something wrong in the structure)
• can you please share any working commands + output (hidden results names anything you need of course)
• finally is your looker instance enterprise big, i.e to the 100k+ lines

I have followed you advice and here is my env with python3.8

(looker-cleanup-py3.8) ~/codebase/looker_cleanup $ poetry show
attrs              23.2.0   Classes Without Boilerplate

I'm trying to make it work and the pulse command is Testing connection 1/6 and never ends and the rest like analyze get some errors, like the below one and others!

(looker-cleanup-hhkCuwdM-py3.8) ~/codebase/looker_cleanup $ henry analyze projects --save --config-file=config.ini

    if "/bare_models/" in cast(str, p.git_remote_url):
TypeError: argument of type 'NoneType' is not iterable

Thanks a lot in advance!

Hey @vasilis-mourtakos , The above error was associated with Henry's inability to connect to my Looker API. I could not get Henry to connect with python3.8 invironment. Instead, I used Python 3.7, and it is working for me as described above.
 
One important thing to note is that the pulse command did not work even after I finally established a connection.

After looking into the error traceback and checking the code, I discovered that there was a small error in the code. Please look Here, in line 81 the two elements in the list need to be separated by quotation marks. You will need to edit the line to look like this: fields=["dashboard.title", "query.count"],

There is another error that needs to be addressed in order to fix the vacuum, and I think the analyze commands and make them work. Please check the following thread, as pointed out by Sedosa Here 

I hope this helps !

@rePetko Thank you so super much for the very detailed and specific answer!
Will try them all and fingers crossed!

Thanks again!
