Adding "Public" fails in the Web UI

[clacke]

This is on https://microca.st/clacke .

I write a post in the Web UI, and I want to make it public. I type "ub" in the "To:" field. The spinner starts. Nothing happens. I type "pu". Same result. I type "public". No change.

Now I've taken a look at the web console, and here is what I see. It's trying to get following?q=public and it gets a 500:

This could be considered two issues:

• The front-end does not handle a back-end 500 -- does not stop the spinner and does not report an error.
• The back-end 500 happens.

[clacke]

Confirmed that whatever I type, I get the same 500.

Sounds like some db corruption... probably extremely tricky to debug. Can anyone confirm whether this happens with a different microca.st account?

[clacke]

https://microca.st/clacke_testing has no trouble.

My microca.st alter ego has no issues with adding "Public" to the "To" field, and it's basically instantaneous.

@clacke, did you try with a completely new browser profile/different "OS user", etc?

[clacke]

I tried two different browsers. But reading the stacktrace tea leaves, it really looks like a join-like operation in mongo-databank is not robust enough. I am following some person who has disappeared from the database.

EDIT: No, that's too fast of a conclusion. The lookup of this unknown user seems to be coming from Pump, not from the databank internally.

[strugee]

If you're following some person who has disappeared from the database, they clearly have not completely disappeared. This of strongly indicative of database inconsistency which suggests corruption. That being said, the fact that it's corrupt in the first place is clearly a bug that we should fix.

Just going to plain https://microca.st/clacke/following produces a different error:

EDIT: No, it's the same with or without ?q=..., just the corruption has changed shape, or maybe pump.io was upgraded to do something slightly different, since last time I looked.
