Error "unexpected |" when connecting to server

[sschuchlenz]

I've started an expose server on port 8083 (let's say my domain is domain.tld) with php7.4 which shows as running. As soon as I try to either connect a local site to it or try to access http://expose.domain.tld, the server crashes with the following error message:

In CacheItemInterface.php line 104:
syntax error, unexpected '|', expecting variable (T_VARIABLE)

This must be coming from one of the dependencies requiring PHP 8. Did you try composer update?

Not yet, thanks for the hint, I'll check

Upgrading to PHP 8 solved this issue for me.

Attached is the full stack showing the source of the error. I'm not a PHP dev - but I'll keep investigating.

Is it not at all possible to run self-host expose on php7.4? The client seems to work fine on 7.4.. not the server? Has anyone made a fork that works on 7.4?
