Please enable debug output and paste a backtrace.

I enable debug and I have these messages in the server.log :

So this raises the question of how the player's coordinates somehow became strings...

[dktapps]

Could you tell us which plugins you have in use on the server?

[LCraftPE]

My plugin... Do you want to have the corresponding file?

[dktapps]

I meant a list of plugins in use on the server.

I have this problem too.
It's happens, when I create Position with string values, such as
$player->teleport(new Position(("-400", "20", "-120", $this->level));
But when I convert string to int:
$player->teleport(new Position(((int)"-400", (int)"20", (int)"-120", $this->level));
this code works good o.0

[knownunown]

That's because they have to be ints. You're simply casting the strings to ints.

[dktapps]

This will become less confusing as the core becomes strict typed.
