This is a somewhat faithful transplation of the original source code, which would not work on 1.8.x, this should desync your inventory too.
function __require(path) { if (path.startsWith("@embedded")) { return globalThis } if (path.startsWith("@minecraft-yarn-definitions/types/")) { return { [path.substring(path.lastIndexOf("/") + 1)]: Java.type(path .replaceAll("@minecraft-yarn-definitions/types/", "") .replaceAll("/", ".") ) } } return require(path); } var exports = {} "use strict"; Object.defineProperty(exports, "__esModule", { value: true }); // imports /* eslint-disable unused-imports/no-unused-imports */ const _embedded_1 = __require("@embedded"); /* eslint-enable unused-imports/no-unused-imports */ // DO NOT TOUCH ANYTHING ABOVE THIS LINE, also not sure why it didn't work const PlayerInteractItemC2SPacket_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/network/packet/c2s/play/PlayerInteractItemC2SPacket"); const UpdateSelectedSlotC2SPacket_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/network/packet/c2s/play/UpdateSelectedSlotC2SPacket"); const UpdateSelectedSlotS2CPacket_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/network/packet/s2c/play/UpdateSelectedSlotS2CPacket"); const Items_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/item/Items"); const Hand_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/util/Hand"); const script = _embedded_1.registerScript.apply({ name: "no-pearl-use", version: "1.0.0", authors: ["commandblock2"] }); script.registerModule({ name: "no-pearl-use", description: "cancels ender pearl use", category: "Player", }, (mod) => { var slot = 0; mod.on("enable", () => { var _a, _b; slot = (_b = (_a = _embedded_1.mc.player) === null || _a === void 0 ? void 0 : _a.inventory.selectedSlot) !== null && _b !== void 0 ? _b : 0; }); mod.on("packet", (event) => { var _a; if (event.packet instanceof UpdateSelectedSlotS2CPacket_1.UpdateSelectedSlotS2CPacket) { slot = event.packet.slot(); } if (event.packet instanceof UpdateSelectedSlotC2SPacket_1.UpdateSelectedSlotC2SPacket) { slot = event.packet.selectedSlot; } if (event.packet instanceof PlayerInteractItemC2SPacket_1.PlayerInteractItemC2SPacket && ((_a = _embedded_1.mc.player) === null || _a === void 0 ? void 0 : _a.inventory.main[slot].item) == Items_1.Items.ENDER_PEARL) { // use reflection to set the hand to offhand const field = event.packet.class.getDeclaredField("hand"); field.setAccessible(true); field.set(event.packet, Hand_1.Hand.OFF_HAND); _embedded_1.Client.displayChatMessage(`§cPearl use changed to hand ${event.packet.hand}`); } }); });original typescript code

This will indeed cancel the usage of the pearl on 1.8.x protocols
function __require(path) { if (path.startsWith("@embedded")) { return globalThis } if (path.startsWith("@minecraft-yarn-definitions/types/")) { return { [path.substring(path.lastIndexOf("/") + 1)]: Java.type(path .replaceAll("@minecraft-yarn-definitions/types/", "") .replaceAll("/", ".") ) } } return require(path); } var exports = {} "use strict"; Object.defineProperty(exports, "__esModule", { value: true }); // imports /* eslint-disable unused-imports/no-unused-imports */ const _embedded_1 = __require("@embedded"); /* eslint-enable unused-imports/no-unused-imports */ // DO NOT TOUCH ANYTHING ABOVE THIS LINE, also not sure why it didn't work const PlayerInteractItemC2SPacket_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/network/packet/c2s/play/PlayerInteractItemC2SPacket"); const UpdateSelectedSlotC2SPacket_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/network/packet/c2s/play/UpdateSelectedSlotC2SPacket"); const UpdateSelectedSlotS2CPacket_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/network/packet/s2c/play/UpdateSelectedSlotS2CPacket"); const Items_1 = __require("@minecraft-yarn-definitions/types/net/minecraft/item/Items"); const script = _embedded_1.registerScript.apply({ name: "no-pearl-use", version: "1.0.0", authors: ["commandblock2"] }); script.registerModule({ name: "no-pearl-use", description: "cancels ender pearl use", category: "Player", }, (mod) => { var slot = 0; mod.on("enable", () => { var _a, _b; slot = (_b = (_a = _embedded_1.mc.player) === null || _a === void 0 ? void 0 : _a.inventory.selectedSlot) !== null && _b !== void 0 ? _b : 0; }); mod.on("packet", (event) => { var _a; if (event.packet instanceof UpdateSelectedSlotS2CPacket_1.UpdateSelectedSlotS2CPacket) { slot = event.packet.slot(); } if (event.packet instanceof UpdateSelectedSlotC2SPacket_1.UpdateSelectedSlotC2SPacket) { slot = event.packet.selectedSlot; } if (event.packet instanceof PlayerInteractItemC2SPacket_1.PlayerInteractItemC2SPacket && ((_a = _embedded_1.mc.player) === null || _a === void 0 ? void 0 : _a.inventory.main[slot].item) == Items_1.Items.ENDER_PEARL) { event.cancelEvent(); } }); });This will desync your inventory with the server anyway, but it is true that no end pearl will be thrown if you have one in your hand (unless u have a pearl in server side but not client side). Can be used as a example.
Later is the original ts file.// imports /* eslint-disable unused-imports/no-unused-imports */ import { Setting, Vec3i, Vec3d, MathHelper, BlockPos, Hand, RotationAxis, mc, Client, RotationUtil, ItemUtil, NetworkUtil, InteractionUtil, BlockUtil, MovementUtil, ReflectionUtil, ParameterValidator, UnsafeThread, registerScript } from "@embedded"; /* eslint-enable unused-imports/no-unused-imports */ // DO NOT TOUCH ANYTHING ABOVE THIS LINE, also not sure why it didn't work import { PlayerInteractItemC2SPacket } from "@minecraft-yarn-definitions/types/net/minecraft/network/packet/c2s/play/PlayerInteractItemC2SPacket"; import { UpdateSelectedSlotC2SPacket } from "@minecraft-yarn-definitions/types/net/minecraft/network/packet/c2s/play/UpdateSelectedSlotC2SPacket"; import { UpdateSelectedSlotS2CPacket } from "@minecraft-yarn-definitions/types/net/minecraft/network/packet/s2c/play/UpdateSelectedSlotS2CPacket"; import { Items } from "@minecraft-yarn-definitions/types/net/minecraft/item/Items"; const script = registerScript.apply({ name: "no-pearl-use", version: "1.0.0", authors: ["commandblock2"] }); script.registerModule({ name: "no-pearl-use", description: "cancels ender pearl use", category: "Player", }, (mod) => { var slot = 0 mod.on("enable", () => { slot = mc.player?.inventory.selectedSlot ?? 0; }) mod.on("packet", (event) => { if (event.packet instanceof UpdateSelectedSlotS2CPacket) { slot = event.packet.slot(); } if (event.packet instanceof UpdateSelectedSlotC2SPacket) { slot = event.packet.selectedSlot; } if (event.packet instanceof PlayerInteractItemC2SPacket && mc.player?.inventory.main[slot].item == Items.ENDER_PEARL ) { event.cancelEvent(); } }) })
