[v4] result is undefined when using _safeParse with rollup

[danny-boyer]

versions:
"@zod/core": "~0.11.6" "zod": "4.0.0-beta.20250505T195954"

Here is the generated code from rollup below

function _safeParse(schema, value, _ctx) {
    const ctx = _ctx ? { ..._ctx, async: false } : { async: false };
    const result = schema._zod.run({ value, issues: [] }, ctx);
    if (result instanceof Promise) {
        throw new $ZodAsyncError();
    }
    return (result.issues.length
        ? {
            success: false,
            error: new (this?.Error ?? $ZodError)(result.issues.map((iss) => finalizeIssue(iss, ctx, config()))),
        }
        : { success: true, data: result.value });
}

Cannot read properties of undefined (reading 'issues')

Is anyone able to reproduce this?

Rollup config

const commonjs = require("@rollup/plugin-commonjs");
const { nodeResolve } = require("@rollup/plugin-node-resolve");

module.exports = {
  input: {
    "order-action": "pos/targets/order-action.js",
    "order-modal": "pos/targets/order-modal.js",
    "smart-grid-modal": "pos/targets/smart-grid-modal.js",
    tile: "pos/targets/tile.js",
  },
  output: { dir: process.env.ROLLUP_OUTPUT_ROOT },
  plugins: [commonjs(), nodeResolve()],
};

What's the code that you're bundling? Difficult to debug this otherwise.

Please also upgrade to the latest beta before you try again. You'll need to update your imports to zod/v4: https://github.com/colinhacks/zod/pull/4364

This is unrelated to zod, the problem was that our process was bundling with rollup which was then bundled by a third party which had zod as well. So two zods of different versions were bundled.
