API stopped working

[bmduarte]

Hi

Without changing any configuration or code, the API requests that were working previously have stopped responding. I also tried creating a new session, and the same problem occurs.

Here's an example:

http://localhost:3001/client/getContacts/sesstest

{"success":false,"error":"Evaluation failed: TypeError: Cannot read properties of undefined (reading 'getContacts')\n at pptr://puppeteer_evaluation_script:2:34"}

Is anyone else having similar issues?

Thanks!

Hello,

I’ve been using the API successfully, but recently the sendMessage endpoint stopped working.
When calling this endpoint, the request no longer sends messages as expected.

• Environment:

  • Node.js: v20.19.3
  • OS: Ubuntu (systemd service)
  • API version: (please fill with the repo version/commit you are running)

• What I expected: A message to be delivered when calling /sendMessage.

• What actually happened: The request returns without error, but the message is not delivered.
  Additionally, I see this error in the logs:

Evaluation failed: TypeError: Cannot read properties of undefined (reading 'sendSeen') at pptr://puppeteer_evaluation_script:7:37

Could you please check if this is a known issue or if there were recent changes affecting the sendMessage endpoint?

Thank you in advance!

@BetoCR @bmduarte WhatsApp keeps updating the wwebjs page, so you need to manually bump the whatsapp-web.js version or feel free to switch to the forked project https://github.com/avoylenko/wwebjs-api

just run npm i whatsapp-web.js and it will work .... like avoylenko said, just update the whatsapp-web.js version

Perhaps I should have run the npm command inside the container but on my Ubuntu server It does give a lot of errors

added 631 packages, and audited 632 packages in 20s

120 packages are looking for funding
  run `npm fund` for details

15 vulnerabilities (2 low, 2 moderate, 10 high, 1 critical)

Maybe should include I am using Docker where possible the npm command is not required but most likely after an update on the Whatsapp side it stopped working.
