Build Basics / Standard term
Error message and logs
An error message reports a detected failure; logs record selected events and context emitted by software over time.
An error may include a type, message, stack trace, status, or cause, but it can be vague, misleading, or far from the originating defect. Logs can show requests, state transitions, timings, and dependency failures when the application was instrumented to record them. Neither source is automatically complete or safe to share.
Builder example
Exact errors and correlated logs narrow a diagnosis, especially when they include timestamps, request IDs, versions, and affected inputs. Before sharing them with an AI service or another person, remove credentials, personal data, tokens, and unrelated customer records.
Common confusion: An error message reports a single failure at one moment, while logs are the continuous record of everything the project did, including normal activity. The error tells you what broke; the logs tell you the sequence and conditions that led there, which is why you read them together rather than treating either as the whole picture.
