Custom dimension portal teleport problem with Y coordinate

Hi, I was working on a portal other than the nether one, when I pass through the portal it teleports me to the correct X and Z but it teleports me to the first saved Y and does not update it in the loop, I also tried to use "is block solid" but it did not work. Can anyone help me? The dimension type is overworld.
