Oxygen's doesn't like spaces in the path to its working directory.

[Kevin Jacob]

Oxygen Fails to Run Tests When the working directory has spaces in the path.
It fails to run the tests and create the output files when there is a space in the directory.

Example:

(virtualenv) kevinjacob@Kevins-MacBook-Pro robotframework-oxygen % robot --listener oxygen.listener tests/atest/oxygen_junit_tests.robot==============================================================================

Debugging this error by:

says :
zsh: no such file or directory: /Users/kevinjacob/Documents/Ongoing

The Folder structure had a space in the folder called Ongoing Projects

Could not replicate the exact error messages but found the root issue with this:

The test case in question is using the green testing tool to process the xml file. green has a bug where you can't give it arguments with spaces, whether you escape them or not. Therefore if any of the test result files has spaces in the path, there is no way to use green with them.

Thanks @JooKop , the issue is thus resolved
