Unable to create browserbase session in nextjs backend

[KenjiPcx]

When I try and request a browser base agent with a nextjs app
const session = await bb.sessions.create({
projectId: process.env.BROWSERBASE_PROJECT_ID!,
browserSettings,
keepAlive: true,
region: getClosestRegion(timezone),
timeout: 600,
});

I get this error

Error creating session: TypeError: (0 , __TURBOPACK__imported__module__$5b$project$5d2f$node_modules$2f2e$pnpm$2f40$browserbasehq$2b$sdk$40$2$2e$4$2e$0$2f$node_modules$2f40$browserbasehq$2f$sdk$2f$_shims$2f$registry$2e$mjs__$5b$app$2d$route$5d$__$28$ecmascript$29$__.getDefaultAgent) is not a function

It's complaining the getDefaultAgent is not a function for some reason

Any ideas how I can fix this?

Moved it to the cua repo browserbase/cua-browser#10

Not sure why it was moved to browserbase/cua-browser#10

It is still a problem on NextJS 15.2.3.
Turning off turbopack (as suggested in that other issue), while a great workaround, isn't a real solution as turbopack is critical for bigger apps.

Any suggested workarounds?

v2.5.0 of this library works around this issue. Please upgrade and give it a try.
