Based on the provided logs, you are running a vanilla server. Advancements are loaded through a mod (triumph), which will not work on a vanilla server, so the server considers them not to exist.

Further, you shouldn't need to copy a single player world to a properly configured server. It is able to generate any of the world types available in single player; you can choose which by setting up server.properties as described in the Multiplayer Instructions.

It looks like pebblehost has an automatic modpack installer, so I'd start by trying that. Otherwise, you can download the server pack from Curseforge, run the installer on your own computer, rename the forge jar to custom.jar and then upload everything to pebblehost, including all the mods, configs and scripts.
