Type application/netcdf is already registered as a variant of application/netcdf

Question

I have a standard rails app on rails 7 and I'm seeing this warning but not even sure where it comes from, any idea?

Type application/netcdf is already registered as a variant of application/netcdf.

There is currently an issue in the mime-types-data gem related to a duplicate definition of this mime type. If you look inside your Gemfile.lock file, you’ll probably find this gem used as a dependency. Luckily, this is just a warning without any consequences. Possible solutions are discussed in the issue.
