Expiration date must be an integer, a DateInterval or null, "double" given

[zzzzBov]

I've just updated to latest and now convertTtl is failing with the following error message:

Expiration date must be an integer, a DateInterval or null, "double" given

/system/src/Grav/Framework/Cache/CacheTrait.php

     */
    protected function convertTtl($ttl)
    {
        if ($ttl === null) {
            return $this->getDefaultLifetime();
        }
 
        if (\is_int($ttl)) {
            return $ttl;
        }
 
        if ($ttl instanceof \DateInterval) {
            $ttl = (int) \DateTime::createFromFormat('U', '0')->add($ttl)->format('U');
        }
 
        throw new InvalidArgumentException(
            sprintf(
                'Expiration date must be an integer, a DateInterval or null, "%s" given',
                \is_object($ttl) ? \get_class($ttl) : \gettype($ttl)
            )
        );
    }
}

I believe checking for a double and either converting it to an int or returning it as-is may solve the issue:

if (\is_int($ttl)) {
    return $ttl;
}

if (\is_double($ttl)) {
    return intval($ttl);
}

...but I don't know enough about the rest of the system to verify that that is a safe change.

Can you please turn on full Error Logging in system.yaml, and provide a screenshot of the stack trace? I really want to know where this double is coming from. Cheers.

Here's the stack trace from the logs slightly cleaned up.

Is this Grav install from github where you had to install vendor libraries manually? I suggest running:

$ composer install --no-dev

to ensure your vendor libraries are up to date?

Alternatively, you can try downloading a fresh Grav package from https://getgrav.org/downloads, and then simply copying over your user/ folder from old site to the new site.
