For some reason on two different non-Meta forums, this exact message cannot be sent in chat:

Removing either the ??? from the first line, or the last line of that log snippet causes it to send properly.

For some reason, I cannot reproduce this on Meta however.

It causes the error both at https://forum.obl.ong/ and https://amcforum.wiki/, it causes a 500 error, logs from AMC are:

Kinda long log

Es wird versucht, in die Chat-Tabelle einzufügen, und die Spalte ist auf 1000 Zeichen begrenzt.

Versuchen Sie es vielleicht hiermit im Data Explorer:

SELECT
    column_name,
    data_type,
    character_maximum_length
FROM
    information_schema.columns
WHERE
    table_name = 'chat_messages'
    AND column_name IN ('cooked', 'message')

Gibt es eine maximale Länge, die irgendwie in Ihrem Schema definiert ist?

Der Fehler value too long for type character varying(1000) deutet für mich darauf hin, dass er mit dem Exzerpt zusammenhängt. Das ist überraschend, da wir Exzerpte technisch auf 150 Zeichen begrenzen, dieser Fall also nie eintreten sollte. Zuerst dachte ich, es sei ein Fehler in unserem Exzerpt-Builder, aber als ich mir den Exzerpt-Code im Chat angesehen habe, sah ich Folgendes:

def build_excerpt
  # Zeige nur die URL an, wenn die gesamte Nachricht eine URL ist, da wir keine Oneboxen aus Exzerpten erstellen können
  return message if UrlHelper.relaxed_parse(message).is_a?(URI)

  # Nur-Upload-Nachrichten werden besser durch den Dateinamen dargestellt
  return uploads.first.original_filename if cooked.blank? && uploads.present?

  # Dies kann für einige komplexe Dinge wie Zitate leer zurückgeben, das ist akzeptabel
  PrettyText.excerpt(cooked, EXCERPT_LENGTH, strip_links: true, keep_mentions: true)
end

Schnelles Debugging hat gezeigt, dass wir PrettyText.excerpt tatsächlich nie erreichen und beim ersten return stoppen. Anscheinend denkt unser Code wegen der ???, dass es sich um eine URL handelt:

[1] pry(main)> UrlHelper.relaxed_parse("???\ntest").is_a?(URI)
=> true

Wir haben die Korrektur identifiziert, aber es wird einige Zeit dauern, bis sie im Main-Branch landet.
