I temporarily found the problem myself and came up with a solution. When I delete the "session" folder and open it again, the problem is fixed, but I have to do this every time I open and close the bot or it crashes. I need a permanent solution can you please help?

[doofzoff]

same, help pls

[loliuy]

same when use TRANSCRIPTION_MODE=openai, and when use !dalle ,also shows the error .

[ImmortalMan01]

It crashes when they send pictures, not just audio files.

It crashes when they send pictures, not just audio files.

yep, or if somebody send stickers, video, photo, gif and more

[rikuddo91]

It also seems to be crashing with !dalle prompt. Only text prompts seems to be working for me. Deleted the sessions folder and relinked whatsapp, but still same error.

[renancunhasousa]

I fix it

declare for window.Store.DownloadManager.downloadAndDecrypt function name change at window.Store.DownloadManager.downloadAndMaybeDecrypt

\node_modules\whatsapp-web.js\src\structures\Message.js line 406

[renancunhasousa]

I change also Injected.js // window.Store.MediaPrep = window.mR.findModule('MediaPrep')[0]; window.Store.MediaPrep = window.mR.findModule('prepRawMedia')[0]; Thank You It's working.

[loliuy]

I change also Injected.js // window.Store.MediaPrep = window.mR.findModule('MediaPrep')[0]; window.Store.MediaPrep = window.mR.findModule('prepRawMedia')[0]; Thank You It's working.

Go to the dowloadMedia function and find the following line: const decryptedMedia = await window.Store.DownloadManager.downloadAndDecrypt

Replace with this:

const decryptedMedia = await window.Store.DownloadManager.downloadAndMaybeDecrypt

[cce15]

It works thank you all

[navopw]

Shoule be fixed with the latest version of whatsapp-web.js I think.

[guerra2fernando]

change to in the package.json to "whatsapp-web.js": "1.21.1-alpha.1"
