keep getting the following error message in my project in VSC

have the path defined in settings.json:
"fortran-ls.executablePath": "C:\Users\Username\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\Scripts",

and also in the XXXX.code-workspace the same:
"fortran-ls.executablePath": "C:\Users\Username\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\Scripts",

have the path in the evnironment variable PATH and also created a environment variable named fortls that its value is:
C:\Users\Username\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\Scripts

installed python so could use pip to install the fortran-language-server:
pip install fortran-language-server

the versions

python --version
Python 3.9.9

fortls --version
1.12.0

gfortran --version
GNU Fortran (GCC) 9.2.0

is there any step/s that am missing?

I just spend some time getting this to work on my linux machine. It should actually be enough to just set the fortran-ls.executablePath setting in any (even bound to the workspace) settings.json file.

I think the problem you have is that you have to provide the path to the executable itself, not just the containing folder.
So it'd be:

"fortran-ls.executablePath": "C:\\Users\\Username\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\\LocalCache\\local-packages\\Python39\\Scripts\\fortls"

Also, change your single backslashes to double, as stated under "Configuration" here: https://marketplace.visualstudio.com/items?itemName=hansec.fortran-ls

My problem was, that I didn't provide an absolute path in the settings, but relative to the workspace. That didn't work.
Hope this helps.
