Clojurians Log v2

Anyone has an idea why my cookie is returned to the browser as a url-encoded string? The session cookie is fine:

set-cookie:
de.bar.foo=MloVXtarzvZz7cNK%2Bri1OK0AKcDbJCcoQdg%2B%2BokPnUUQsL%2F0Hv2sZ8v8dUth5nqMbA%2FdmCbQAaiDss0JdukNQyH25%2Fh1i%2Fi33nF6ctcEFz%2BPOq9vnvb6r8vbx3PkMZHK--QV%2FG6g5xD2NIm2v76u2hojbngSj7%2BBg%2FouWBHF%2FF1t0%3D; Path=/; HttpOnly; Max-Age=86400; SameSite=Lax

the cookie-consent-cookie is bad:

set-cookie:
cookie-consent=value=accepted&path=%2F&max-age=31536000
