This issue might be a duplicate of existing issues. Please check:

• z.ai usage limit.The full error message from the api is not shown in desktop opencode app. #13478: Similar report of usage limit errors not being properly shown in the web/desktop app (open, labeled web)
• No errors when usage limit is reached (Claude Pro) #777: Usage limit reached with no notification shown (closed)

If your issue is distinct from these (e.g., a regression or a different web app behavior), please clarify in a comment.
