Hi  
I am using AWX 1.0.2 on rhel7.4 and i using ansible v2.4.2. My AWX installattion method is docker on linux.

I am facing an issue on AWX GUI while launching the job template: “Failed updating job undefined with variables. POST returned: 500 A server error has occurred”  
When i checked awx\_web container logs it is showing below errors:

File “/usr/lib/python2.7/site-packages/awx/main/managers.py”, line 88, in me  
raise RuntimeError(“No instance found with the current cluster host id”)  
RuntimeError: No instance found with the current cluster host id

Please help

Thanks & Regards  
Soniya

Soniya,

You’re likely encountering a bug that was resolved in a recent version of AWX:

[https://github.com/ansible/awx/pull/4268](https://github.com/ansible/awx/pull/4268)

The version of AWX you’re on is two years old now - you should consider upgrading to the latest version to resolve this and many other issues (including critical security issues).
