puzzling waitUntil warning

For the life of me, I'm not sure what part of my code is causing this. The result appears to be a handful of openai calls that are immediately failing, so I'm doing something wrong. I've bundled my async code into a single function which returns via return Promise.all(promises) to ctx.waitUntil() in my fetch. Running it locally (see screenshot) is also indecipherable. tail logs:

  "exceptions": [],
  "logs": [
    {
      "message": [
        "Missing `waitUntil` option."
      ],
      "level": "warn",
      "timestamp": 1723243628284
    }
  ],

  "logs": [
    {
      "message": [
        "Missing `waitUntil` option."
      ],
      "level": "warn",
      "timestamp": 1723243628284
    }
  ],

index.ts

    async fetch(_: FetchEvent, env: Env, ctx: ExecutionContext) {
        const scheduledSync = new ScheduledSync(env)
        ctx.waitUntil(scheduledSync.sync())
        return new Response('ok')
    },

    async fetch(_: FetchEvent, env: Env, ctx: ExecutionContext) {
        const scheduledSync = new ScheduledSync(env)
        ctx.waitUntil(scheduledSync.sync())
        return new Response('ok')
    },

sync.ts (truncated)

export default class ScheduledSync {
    private env: Env

    constructor(env: Env) {
        this.env = env
    }

    public async sync(): Promise<any> {
        let results: any = []
        // truncated for clarity:
        const users = await g.query<User>('SELECT * FROM echo.dim_users WHERE name iS NOT NULL AND name <> ""') // owners/teammates for this org

        results = results.concat(
            Promise.all(
                users.map((user) => {
                    // ...
                    return v.upsert(`user:${user.source_system}:${user.user_id}`, text, meta)
                })
            )
        )
        return results
    }
}

export default class ScheduledSync {
    private env: Env

    constructor(env: Env) {
        this.env = env
    }

    public async sync(): Promise<any> {
        let results: any = []
        // truncated for clarity:
        const users = await g.query<User>('SELECT * FROM echo.dim_users WHERE name iS NOT NULL AND name <> ""') // owners/teammates for this org

        results = results.concat(
            Promise.all(
                users.map((user) => {
                    // ...
                    return v.upsert(`user:${user.source_system}:${user.user_id}`, text, meta)
                })
            )

        return results
    }

https://github.com/kriasoft/web-auth-library/blob/42a722e4cedc09ea2a86f92fe5aed73b19e5de94/google/accessToken.ts#L21 looks like you maybe using this lib which is expecting waitUntil passed in
