@PaulRitzkat do you have a host with a / character in it? How are you importing your inventory?

[ryanpetrello]

@PaulRitzkat this is actually a bug in ansible itself: https://github.com/ansible/ansible/issues/41413
I'm going to add some code in awx to detect this scenario and cause awx to fail more gracefully (by skipping fact gathering for hosts that contain an / in their name).

[PaulRitzkat]

@ryanpetrello interesting. This could be the case, I'll check it tomorrow and get back to you. The inventory is imported via awx-manage.
I did limit the template to one hosts with no / or other special chars in its name and it failed too.

[ryanpetrello]

@PaulRitzkat in this case, the limit shouldn't make a difference. I'm going to contribute a change in the near future that will make awx more gracefully handle this scenario, here; I won't be able to fix caching for hosts that contain /, but I _can_ make the _other_ working hosts in the inventory cache properly.

@PaulRitzkat we've just released 1.0.7, which we believe resolves the underlying issue here. You can try it out here: https://github.com/ansible/awx/releases/tag/1.0.7

Let us know if you're still seeing this issue after installing the latest awx - thanks!
