Bug Description

When trying to create a new Sticker pack, as soon as i want to upload the pack the error "cannot read property 'encryptAttachment' of undefined" appears and no upload seems to happen.

Steps to Reproduce

1. Open the sticker pack creator
2. Add stickers from https://gitlab.com/betalars/helpful-recources/-/tree/master/Mental_health_stickerpack/stickers
3. Assign emojis
4. Set name, author and icon
5. Press continue
6. Press upload

Actual Result:

For a few seconds, a box appears on the right side of the cancel button saying: Error uploading stickers: cannot read property 'encryptAttachment' of undefined.
Repeating the process results in the same behavior.

Expected Result:

Stickers are uploaded.

Thanks for the bug report. We'll have a fix in the next beta release.

I had the same issue on v1.34.0-beta.1. On v1.34.0-beta.3 no such error occurs.

@williamvds How did you install Signal Desktop?

@williamvds How did you install Signal Desktop?

Via the Arch User Repository package which pulls builds directly from https://updates.signal.org. I suspect @moonlies did the same.

I just tested the sticker creation process on v1.34.2 on Ubuntu 18.04. This appears to be due to the packaging process used in the creation of the Arch package. I'm going to close this.
