Use of undefined constant PASSWORD_ARGON2I

[MatTheCat]

Seems like #521 was not enough: after upgrading my image I get

Use of undefined constant PASSWORD_ARGON2I

No idea why though.

Meanwhile I keep using sodium but it bother me to use it for argon only!

That is strange, it seems to work here. Maybe the image had not been pushed yet?

I tried again and same error. Here is my Dockerfile's diff:

Do you see any issue? I'm using docker-compose up -d --build after that to update and launch some containers maybe there's a cache somewhere..?

I ran docker-compose build --pull and now everything is working as expected. What does this command docker-compose up -d --build doesn't?
