[ERR_REQUIRE_ESM]: require() of ES Module \node_modules\srt-parser-2\dist\index.js from langchain\dist\document_loaders\fs\srt.cjs not supported

[ladrians]

I am trying to update to version 0.1 from 0.0.214. I am receiving the following error

C:\temp\packages\functions\node_modules\ts-node\dist\index.js:851
            return old(m, filename);
                   ^

Instead change the require of index.js in C:\temp\packages\functions\node_modules\langchain\dist\document_loaders\fs\srt.cjs to a dynamic import() which is available in all CommonJS modules.

from this code, noticed the srt-parser-2 dependency was updated.

import { SRTLoader } from "langchain/document_loaders/fs/srt";
...
documentLoader = new  SRTLoader(filePath);
...

thanks,

Hi, @ladrians,

I'm helping the langchainjs team manage their backlog and am marking this issue as stale. The issue was opened by you and is related to the srt-parser-2 dependency being updated, causing an error related to ES Module support. There were discussions about resolving the issue by changing the require of index.js in srt.cjs to a dynamic import() and trying to upgrade the peer dependency to the latest version. You confirmed that the issue persists with the latest version and provided a minimal sample to reproduce it.

Could you please confirm if this issue is still relevant to the latest version of the langchainjs repository? If it is, please let the langchainjs team know by commenting on the issue. Otherwise, feel free to close the issue yourself, or the issue will be automatically closed in 7 days.

Thank you for your understanding and cooperation. If you have any further questions or need assistance, feel free to reach out.

Does this persist if you upgrade your peer dependency to the latest version?

I think this is related to folks running into #1554. Unfortunate that there was a breaking change in a patch in that package.

Please reopen if that doesn't fix it.

[ladrians]

yes it does, not sure how to WA it.

I have the latest 1.2.3 version. This is a minimal sample to reproduce it

import { SRTLoader } from "langchain/document_loaders/fs/srt";

export const run = async () => {
  const loader = new SRTLoader(
    "c:/temp/test.srt"
  );
const docs = await loader.load();
console.log(docs.length);
}
(async () => {
  await run();
})();

using ECMAScript

ts-node --esm -r dotenv/config src/scripts/sandbox.ts

the test.srt file is just

1
00:00:00,000 --> 00:00:02,000
Hello, world!

2
00:00:02,500 --> 00:00:05,000
This is a minimal SRT file.

@jacoblee93 if possible can you reopen it? I do not have the option.
