module 'fes' has no attribute 'Handler'

I've followed the instructions to install fes. Using uptide commands leads to this error:

module 'fes' has no attribute 'Handler'

cmake commands were run from inside the firedrake virtual environment and the testing within the build folder ran successfully. How can it be confirmed that fes has installed correctly within the firedrake folders and is accessible by uptide?

FES changed their API so uptide will need some changes to be made compatible again, see #16.

You can install an older, compatible version of FES by checking out v2.9.7 instead of latest:
pip install --no-build-isolation git+https://github.com/CNES/aviso-fes/@2.9.7

In the same FES v2.9.7 you can find a working ocean_tide.ini. (The link in uptide's README is currently dead since FES renamed the file to .yaml).
