Error when building with contentlayer 0.3.4 and Next.js 13 App Router

[schneedotdev]

When I run pnpm contentlayer build, I run into an error within node_modules and cannot resolve it.

Versions

"contentlayer": "^0.3.4",
"next": "13.4.9",

Error Message

import { ConsoleSpanExporter, SimpleSpanProcessor } from "@opentelemetry/sdk-trace-base";
         ^^^^^^^^^^^^^^^^^^^
SyntaxError: Named export 'ConsoleSpanExporter' not found. The requested module '@opentelemetry/sdk-trace-base' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@opentelemetry/sdk-trace-base';
const { ConsoleSpanExporter, SimpleSpanProcessor } = pkg;

Downgrading to version ^0.3.1 seemed to work. I'm able to run pnpm contentlayer build but the newest version (0.3.4) of contentlayer does not work for me.

Same issue, can confirm it

It's not related to the app router but yes, I'm getting the same error.

I guess that is because both Next.js and Contentlayer use open telemetry as a dependency.
Dependency conflict is likely the cause of the problem.

[fuma-nama]

Confirmed.
I fixed it by overriding dependency versions (using pnpm).

    "version": "0.1.0",

    }
}

@brianschnee it is not related to the App router, but rather to ESM; don't know what contentlayer has changed but the package stopped building properly when using .mjs/ESM. Using 0.3.1 works for me as well.

[ParkerRex]

that pnpm override -- what a great discovery. Wish I looked 3 hours ago haha.

[mauriciomutte]

The same for me... using 0.3.2 works as well but upgrading to 0.3.4 shows the error mentioned

[dgknca]

same error
