Bridge no longer working with Dendrite #457

Closed pix closed 7 months ago

pix commented 7 months ago

Hi.

I was using mautrix-signal as of today when I upgraded by mistake. It seems mautrix-signal / the go bridge library now complain that dendrite is outdated:

mautrix-signal  | 2024-02-18T17:33:55Z DBG Checking connection to homeserver
mautrix-signal  | 2024-02-18T17:33:55Z INF Starting HTTP listener address=0.0.0.0:29328

mautrix-signal  | 2024-02-18T17:33:55Z FTL The homeserver is outdated (supported spec versions are below minimum required by bridge) bridge_requires=v1.4 server_supports=v1.2

It seems related to https://github.com/mautrix/go/blob/b1b1c97a115cf3e8d72c81cdbb090a546df5dbb0/bridge/bridge.go#L319

But I can't find any reference nor traceback the origin of the requirement. Is this deliberate ?

Sincerly yours, C.M.

Strangely, the first broken commit is: https://mau.dev/mautrix/signal/-/commit/d778a14fba2da50758e45928c89aba4093ccbf5a

https://mau.dev/mautrix/signal/-/commit/8de9493edc39cf7be736172fe91d36f6a805eddc is working

Which seems, unrelated...

Dendrite API is lagging behind. tulir has added a flag to the bridge to disregard the version check. That, together with running the latest commits to Dendrite will get the bridge working again.

I am new to signal bridge and I am getting this error and can't onboard. How do I enable this flag mentioned?

I wrote a blog post detailing my steps:

The tldr is that you need a Dendrite version from February 2024 or later (there are no releases as of writing) and use the --ignore-unsupported-server flag for the bridge.
