ERROR_REQUEST_OUT_OF_SEQUENCE
the requested operation is invalid in the component’s current state.
ERROR_REQUEST_OUT_OF_SEQUENCE identifies the condition that this condition The component implements a stateful protocol, and the caller invoked a method before a prerequisite step or after the relevant phase had already finished.
Where the result appears
- initialize-bind-execute-fetch style APIs.
- asynchronous components with pending operations.
- transactional providers.
- objects reused after close, cancel, or completion.
How to interpret the result
Interpret the numeric value in the Win32/LRESULT domain and in the context of the API that returned it. Preserve this result before wrappers convert it to an HRESULT, exception, Boolean failure, or provider-specific message. When recording it, note whether the operation produced usable output; this determines whether the value is completion information, control flow, or a terminal failure.
Diagnostic evidence to collect
- object state immediately before the call.
- complete method sequence with timestamps.
- pending asynchronous callback or completion.
- thread identity when the object is not documented as thread-safe.
A diagnostic record for this Win32 error should contain the API name, input flags, relevant handles or object identifiers, thread and process identity, timestamp, and the immediately preceding state transition. Those fields are more useful than a generic screenshot because they show which contract and lifecycle phase produced the value.
Handling and recovery
Model the API as an explicit state machine and allow each call only in documented states. Serialize access where required and make cancellation and close paths update state atomically.
Retry after this result only when an external state relevant to this operation can actually change. When it is rooted in object state, unsupported capability, ownership, or invalid sequencing, an unchanged retry repeats the defect and can obscure the first useful diagnostic record.
Common misinterpretation
Adding a delay may hide but not fix an ordering defect. The reliable solution is to wait for the documented completion signal or correct the call sequence.
Guidance for developers
Keep the original this result value and its Win32 domain in structured telemetry. If it crosses COM or another HRESULT-based boundary, store both the source Win32 value and the converted result. If it crosses JSON, RPC, or a database boundary, include error_domain, error_code, operation, and object_state so the receiver does not apply a second conversion.
An automated test should construct the specific state that leads to this result, assert the exact returned value, and verify cleanup on both the normal and exceptional path. The result test should additionally prove that the caller does not collapse this status into an unrelated generic error and does not retry forever.
