Map Bedrock Converse unsupported-MIME ValueError chains into a typed UiPathUnsupportedAttachmentError (stable UNSUPPORTED_ATTACHMENT_FORMAT code, preserved mime_type/provider_detail). Dispatch client-side typed errors through a _CLIENT_SIDE_CLASSIFIERS registry tried ahead of HTTP status mapping, so future non-HTTP error propagations are a one-line addition rather than a dispatcher edit.

Summary
UiPathUnsupportedAttachmentErrorwith stableUNSUPPORTED_ATTACHMENT_FORMATerror_code.ValueErrorchains into that typed UiPath error, preservingmime_typeandprovider_detailfor downstream agent-specific mapping._CLIENT_SIDE_CLASSIFIERSregistry, tried ahead of HTTP status mapping (a typed semantic error is more actionable than the raw status). Adding the next non-HTTP error propagation is a one-line append rather than a dispatcher edit.uipath-llm-clientto 1.15.1 (1.15.0 already published without this API).Root cause
Bedrock Converse request conversion can reject file blocks locally with a bare
ValueError("Unsupported MIME type") before any HTTP response exists. The generic provider wrapper previously mapped that to the rootUiPathError, losing the user-actionable attachment semantics.Validation
