[Spaces] Handle and log when space summary requests time out instead of dumping a traceback #10026
Description
Description
I am hosting my own homeserver, while a colleague of mine is using matrix.org's server.
Yesterday, I have accepted an invite to join a Space sent by this colleague. This sort-of worked, but Element told me that Spaces were not enabled on my homeserver. I went and added experimental_features: { spaces_enabled: true } to my synapse, restarted, and the message was gone.
However, I then found out the following errors in my homeserver's logs:

At the same time I realized that while the list of rooms of the space is shown correctly, the list of members of the space only shows my account, and not the account of my colleague who created the space. Not sure this is related though.
Steps to reproduce
- from a custom homeserver, join a space created on matrix.org
- enable the spaces feature on the custom homeserver
- restart
Version information
- Homeserver: my own custom homeserver (I can give the address in private if needed)
If not matrix.org:
-
Version: v1.34.0
-
Install method: docker image
- Platform: debian 10
