404 error on collections endpoints with new forest_liana version

[littletime]

Expected behavior

Our Forest Admin retrieves and displays collections from our server.

Actual behavior

Forest can connect, the login request to our server works, but then we have a 404 when trying to load any of the collections.

Context

We just pushed to production, rebuilding our Docker image, which updated our forest_liana package to the last version (5.2.0). In the meantime, we specified the 5.1.3 version in our Gemfile, and it works as expected.

• Package Version: 5.2.0
• Rails Version: 6.0.2.1
