Description of problem:

When trying to check the rendered content of Discovery Red Hat kexec template, from Provisioning Templates card in the Details tab of a Host in the new Hosts UI, It says Something went wrong and shows a React error

How reproducible:

100%

Is this issue a regression from an earlier version:

Not sure but the same problem exists on 6.14.4 as well. 

Steps to Reproduce:

1. Submit a fake baremetal-host build from satellite webUI or hammer

2. Hosts -> All Hosts --> Click open the Host --> Details --> Provisioning Templates card --> Click on "Discovery Red Hat kexec" 

Actual behavior:

Please see the attached screenshot

The trace shows something like this i.e. 

Error: Minified React error #31; visit https://reactjs.org/docs/error-decoder.html?invariant=31&args[]=object%20with%20keys%20%7Bkernel%2C%20initram%2C%20append%2C%20extra%7D&args[]= for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

But if we go to Hosts --> Provisioning Templates -> Open the Same template and Review it against the same host, It works without any errors. 

Expected behavior:

No such errors for any templates at all.

Business Impact / Additional info:

Due to the nature of the error, A user falsely assumes that something is wrong with their discovery template maybe and leads the investigation in an unwanted direction. The error is not harmful but it definitely is a UI flaw and a very irritating one, as it blocks me to see the rendered content of the discovery template when investigating some issues for a host.
