askvortsov I ran into the same problem - which is solvable by requesting 5.2.5 version of web-push. But then there is another version clash. Is that something that comes with flarum? If so is it safe to downgrade?
`composer require minishlink/web-push:5.2.5
./composer.json has been updated
Running composer update minishlink/web-push

Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires minishlink/web-push 5.2.5 -> satisfiable by minishlink/web-push[v5.2.5].
- minishlink/web-push v5.2.5 requires guzzlehttp/guzzle 6.2 -> found guzzlehttp/guzzle[6.2.0, ..., 6.5.5] but the package is fixed to 7.2.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.`
