As far as I understand, it default to `let` in these cases because the tool cannot figure out if a `const` is possible. It has to be checked manually:

Since this commit 97e2df0a8d tests were broken because the URL has an extra date parameter to update the cache for datalayers. With the new regexp, we match these new URLs with the fakeServer from sinon.
Also update sinon to v15.
