As a person with minimal academic physics experience, I've occasionally wondered if the action of passing mass through a wormhole would violate the conservation of energy.

Say if one side of a wormhole is near an astronomical object, and another in an arbitrary point in empty space, then would the change in potential energy of the transmitted mass due to gravity be converted to another form?

If it were the case that the field of gravity were to be transmissible through a wormhole, then would opening or closing a wormhole consume or release an enormous amount of energy equal to the change in potential energy of the surrounding matter?

I suspect the time dilation could also be an issue, where objects passed through a wormhole are stretched or compressed akin to gravitational spaghettification, or if objects surrounding the wormhole experience time dilation due to the stretched spacetime.

If I'm not mistaken, existing wormhole theories generally require the presence of "negative energy/mass", which I believe is considered to be repelled by gravity instead of attracted to it.

Combined with the fact that, under general relativity, wormholes and gravity both involve significant bending/shaping of spacetime (I think), I imagine it's really difficult to think about how wormholes interact with gravity coming from the perspective of how typical energy/mass does.
