STATUS_CLOUD_FILE_INVALID_REQUEST

An invalid Cloud Files request is a contract error: the requested operation, arguments, placeholder state, or sync-root policy do not form a permitted combination. It differs from STATUS_CLOUD_FILE_NOT_SUPPORTED, which says the provider or policy lacks a capability; here the particular request itself is invalid.

For provider-issued operations, validate the operation type, structure sizes, connection and transfer keys, and the request's range or state assumptions. Some hydration policies explicitly reject operations that would create a non-fully-hydrated placeholder.

Useful checks

Record CF_OPERATION_INFO and CF_OPERATION_PARAMETERS fields with the failure.
Verify every StructSize and policy-dependent precondition before calling CfExecute.
Do not retry unchanged arguments; rebuild the request only after identifying the violated precondition.

Relevant documentation

CfExecute documents the provider entry point and operation structures.
CF_SYNC_POLICIES lists policy combinations that cause invalid placeholder requests.
