Notepad does not work in docker

I started solid in docker, as described in the README, created user alice, went to alice.localhost, logged in, went to Public Folder, clicked plus, selected the Notepad icon. Giving a name leads to:

Error: FAILED to save new tool at: https://alice.localhost:8443/public/Alice/index.ttl : Web error: 500 (Internal Server Error) on PUT of <https://alice.localhost:8443/public/Alice/index.ttl>

Per issue #901, certificate problems might be the cause. However, unlike that issue, I cannot start with option -v: error: unknown option -v

Anyways, I changed the dockerfile to CMD ./bin/solid-test start.

Now, I can create a notebook. However, selecting it and entering text leads to:

Error undefined sending data: Web error: 409 (Conflict) on PATCH of <https://alice.localhost:8443/public/Notepad/index.ttl>

What is supposed to work via docker? Maybe Dockerfile should use solid-test by default?

Inizia con la configurazione Docker descritta nel README e ispeziona il comando predefinito del Dockerfile insieme a bin/solid-test. Riproduci la creazione e la modifica di un blocco note con il container predefinito, quindi confrontale con il comando solid-test segnalato. Il lavoro è completato quando la configurazione Docker documentata supporta la creazione di un notebook e il salvataggio delle modifiche senza gli errori 500 o 409 segnalati.
