抱歉，@Lilly，这个问题应该已经通过

> <https://github.com/discourse/discourse/pull/36735>
>
> When testing a new LLM configuration in the admin panel, if the test fails (e.g.…, invalid API key), users see "Target can't be blank" instead of the actual error from the LLM provider.
> 
> This happens because \`track\_failures\` attempts to create a ProblemCheckTracker using \`llm\_model.id\` as the target, but unsaved models have \`id = nil\`, which fails the \`validates :target, presence: true\` validation.
> 
> The fix adds a \`new\_record?\` check to skip failure tracking for unsaved models, consistent with the existing checks for \`blank?\` and \`seeded?\`.
