"cat: /tmp/tmp.VEwej1syj9: No such file or directory" error in clion debugger. Follow

I'm trying to run the debugger in clion 2020.1.2 but I'm getting the following error: 

```

Testing started at 15:09 ...
D:\libOmexMeta\cmake-build-debug-wsl-ubuntu1804-gcc101\bin\redland-wrapper-tests --gtest_color=no
cat: /tmp/tmp.G22JRIftqz: No such file or directory
cat: /tmp/tmp.VEwej1syj9: No such file or directory
Process finished with exit code 1

```

Everything works as expected if I just run the program, i.e. no debugger. Any idea what's going on here? 

Thanks
