Answer 1

Though it is old question, there is no answer in 5 months. I got similar issue and found the cause for my case.

This issue might be generated due to wrong XML configuration. If you would add more code related to this issue, I probably could isolate the exact reason behind this issue.

At my end, I wrote di.xml wrongly, I didn't write root tag in di.xml. For that reason, this error would generate.

If anybody gets this issue, you should check your configuration files.

Answer 2

The Main Problem Is your command line Is not Working...

And A Firstly Check Your Configuration File Before Not working any Idea Then Do this

This is Create an issue in Di.Xml File If you are only changing a Di.xml File Name Then Problem Solved
