• looker-sdk 0.1.3b7

Successful commands

• pulse
• analyze projects

Any command can be shared and the following error occurs (also on a Mac).

I ran into this fixing a different issue. One culprit was the system__activity model, but there are other cases too I wasn't able to track down.

Here's a consistent failure of this nature: henry analyze explores --model system__activity --config-file ../looker.ini

In this case we're failing here on explores = [self.sdk.lookml_model_explore(model, explore)] here

[emilywilson2]

I'm also getting the same errors on all commands except pulse and analyze projects

Python 3.7.0 henry 0.2.2
looker-sdk 0.1.3b7

[nishiogawakun]

Same set up, same errors as above.

[TiagoCruz1989]

Same here. If i use the name of some models as a parameter it works. If not i get the same errors.

[jcarah]

There is some unknown condition under which Looker's API will return explores in the call to the /models/ endpoint, but those explores can't be found when you make a call the /models/explores endpoint.

Henry makes these call successively, in fetcher.py. On line 157, I updated the except block to simply ignore these mismatches.

except error.SDKError:
    # raise exceptions.NotFoundError(
    #     "An error occured while getting models/explores."
    # )
    print("Could not find explore...skipping.")

@josephaxisa I wonder if you have any idea what's going on and whether you think this is an acceptable workaround. I can make a PR if so.
