moss / MossError

Interface: MossError

A RuntimeError subclass raised for every failure the native core reports. Branch on code, not on the message: the message is fixed text for each kind of failure, such as Index not found., with no URLs, file paths or index names. (moss 1.15.0+, with inferedge-moss-core 0.27.0) InvalidArgumentError is the subclass raised for INVALID_ARGUMENT. Not every exception the SDK raises is a MossError: a closed MossClient raises a plain RuntimeError, a filter value of the wrong type raises TypeError, some argument checks raise a bare ValueError, and web source methods raise ManageApiError (see Web sources). None of these has a code.

Properties

code: Optional[str] - The kind of failure, stable across releases: INVALID_ARGUMENT, NOT_FOUND, UNAUTHORIZED, NETWORK, DESERIALIZATION, MODEL_UNAVAILABLE or INTERNAL. Every MossError the SDK raises sets it. See Error codes.
detail: Optional[str] - The core error text, for logs and support, at most 512 bytes. Released wheels carry it too. Diagnostic text, not a stable contract. None when there is none.

Example

from moss import MossError

try:
    results = await client.query("faqs", "refund policy")
except MossError as e:
    if e.code != "NOT_FOUND":
        raise
    await client.load_index("faqs")
    results = await client.query("faqs", "refund policy")
