500 Error when editing an existing post

Contribute Bug

AI-generated summary

Multiple users, including watchmanmonitor, codinghorror, and clay, have reported encountering a 500 error when editing an existing post, particularly when adding or removing links. The error typically resolves after resubmitting the edit.

The issue has been reproduced on different sites, and the error log shows an ActiveRecord::StatementInvalid error due to a failed SQL transaction. codinghorror notes that the error seems to occur on posts with links in them.

watchmanmonitor has provided a stacktrace and a list of plugins used, including docker_manager, discourse-solved, discourse-feature-voting, discourse-saml, and discourse-slack-official.

sam requests a repro to further investigate the issue but ultimately closes the discussion as stale.

I’ve had this twice now when editing an older topic in my discourse. The second was after a full docker update about 20 minutes ago.

Repro:

  • Find an old article
  • Edit it, in my case making a number of words into http links using command-k and pasting in the URL
  • Save the article

I get a 500 error shown on screen. I try to save again, and it works.

ActiveRecord::StatementInvalid (PG::InFailedSqlTransaction: ERROR:  current transaction is aborted, commands ignored until end of transaction block
: SELECT  "topics".* FROM "topics" WHERE ("topics"."deleted_at" IS NULL) AND "topics"."id" = 1072 LIMIT 1)
/var/www/discourse/vendor/bundle/ruby/2.3.0/gems/rack-mini-profiler-0.10.1/lib/patches/db/pg.rb:93:in `exec'

Stacktrace

I’m using these plugins:

          - mkdir -p plugins
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/discourse/discourse-solved.git
          - git clone https://github.com/joebuhlig/discourse-feature-voting.git
          - git clone --branch watchman-community https://github.com/watchmanmonitoring/discourse-saml.git
          - git clone https://github.com/discourse/discourse-slack-official.git

What might be happening here?

I have been able to repro this a few times on different sites. So it’s a legit bug.

Submitting the edit again usually works so it’s not a terrible bug as bugs go.

Just to amplify this it is sometimes an edit that adds a link where I see the error. Resubmitting works.

For what it’s worth, I just ran across this on my forum today - an older post with a link at the bottom that I was trying to remove. I ended up switching owner to an admin and then editing the post that way.

I just got an error 500 when editing a post on meta. Clicked “save” again without changing anything and it worked fine…

The (not particularly useful) error in the JS console is:

Failed to load resource: the server responded with a status of 500 ()      /posts/313832

I don’t have a repro unfortunately :frowning: but I know this bug exists on edit, sometimes, on posts with links in them.

I’ve been having this a lot recently.

A repro would be enormously helpful here, I can sort of tell what happened, but can not tell how the transaction hit an error state, its like there is a missing error in that log, something that happened prior to the backtrace you posted.

Schließe als veraltet… Entschuldigung.
