local pugin in ansible EE

[OM Nachiketa]

Hi,

I am trying to build an ansible execution environment image with ansible-builder and want to add a local inventory plugin that I have developed. But getting these errors.

An error occured (rc=1), see output line(s) above for details.

Any help would be greatly appreciated.
