Failed to upload QR code - M_UNKNOWN (HTTP 500)

[jakobkilian]

Describe the bug

After updating synapse and mautrix_whatsapp_ynh I lost connection to whatsapp. I reinstalled mautrix_whatsapp_ynh and can now sucessfully speak to the Whatsapp Bridge in Elements (version leads to mautrix-whatsappv0.8.6 (Jun 16 2023, 11:48:57))
When entering login however the response is Failed to upload QR code: failed to POST /_matrix/media/v3/upload: M_UNKNOWN (HTTP 500): Internal server error
I restarted the system and tried to find more logs or hints about the error without success so far.

Context

• Hardware: VPS at hetzner.com
• YunoHost version: 11.1.22
• I have access to my server: SSH, Webadmin, ...
• Using, or trying to install package version: v0.8.6 (before it was Version 0.7.1~ynh1)

Expected behavior

QR Code to connect Whatsapp gets uplaoded

photos sent on whatsapp by third party are not bridged to element
i have an error in synapse

Hi @rosbeef @jakobkilian

I'll have a look on this, maybe something changed API wise and I did not check it properly.
I'll keep you updated 🙂

[thardev]

I took a look on this and regarding the error you posted @rosbeef it could be related to an upstream bug from Synapse.
See: YunoHost-Apps/synapse_ynh#396

Could you tell me which version of Synapse are you using? @jakobkilian @rosbeef

[rosbeef]

Synapse 1.87.0~ynh1

[jakobkilian]

sorry, I have already taken everything down (for other reasons), but I also used 1.87.0~ynh1

[thardev]

Ok, so I'll suggest to wait until it is fixed from upstream and it may be solved here as well. From what I saw in the bug report that I linked it should be solved in the next release (1.88.0)

[rosbeef]

please test it's working today

[thardev]

Hi @rosbeef

I already updated to latest version (1.88.0) and seems to be working fine, I'll close this, feel free to reopen if you experience any issues but also keep in mind that this is a Synapse upstream issue so I cannot do anything about it 🙂
