I'm having same issue... perhaps you should post your question to magento.stackexchange.com – Infallibilism

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.

This is a helpful comment, but probably shouldn't be considered an answer. – Pape

Answer 4

In my case, I missed to add the headers <config> of the di.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
