Hi @lonegunmanb

Thanks for this PR. Please see below for a suggestion on how this could be changed and kept more consistent with implementations in the AzureRM provider.

Additionally, a 404 should result in a non-nil value for err here, did you look into why we are getting into this condition?

Thanks!

Thanks for the updates @lonegunmanb - This LGTM now 👍

Did you find out why we're not getting the err when the response object has a 404 in it?

No, it's weird since the whole Reponse is nil. At the crash point, we do have an err but the core was crashed by this nil Response before we can read err (which means no 404 even), I cannot reproduce the error in my side, maybe we can fix this crash, then ask the user to try agin, then he'll be able to read the actual error and share it with us. Could we merge this patch @jackofallops?

Hi @jackofallops @manicminer is there anything I can do to get this pr be merged? Thanks!

[manicminer]

Hi @lonegunmanb, we appreciate the work on this, however I don't believe the proposed change will resolve the original error and as such I am not convinced this is worth changing in its current state?

[lonegunmanb]

Hi @manicminer , the user is facing a core crash so the actual error cannot be displayed, as we should avoid any nil panic in any case, could we just merge this pr first, so the user could report the actual ereor to us?

[lonegunmanb]

Hi @manicminer, a kindly ping, is there anything I can do to get this pr merged? Or do you have any suggestion to fix the panic? Thanks!
