Jev retrieval failure errors

Retrieval failure is an application error: your search, CRM, or object store did not return the evidence Jev would need. TypeSafe’s classifying-RAG cookbook assumes you already have passages, then scores them. There is no documented TypeSafe status for “Elasticsearch was down.”

Do not call Jev on an empty hit list and pretend the Noul is a relevance search. This site does not sell, issue, or proxy TypeSafe keys. Authenticate with a credential you already have from the console or a documented gateway.

Jev retrieval failure errors: context

System One evaluates the state you send. If retrieval returns nothing, your code should emit retrieval_failure and skip or retry the retriever. If retrieval returns junk, Jev can still assign probabilities — that is a quality problem, which the cookbook addresses with per-passage questions.

Jev retrieval failure errors: inputs

Record retriever id, query, hit count, and passage ids. Only then build state (object or array of passage texts). Filter to what the question needs. English first.

A timeout talking to the index is a retrieval failure, not a Jev timeout — keep the enums separate.

Jev retrieval failure errors: decision logic

Policy example: 0 hits → safe default or human. Some hits → one System One request that scores each passage (fan-out of questions, not of HTTP). Drop passages Jev flags as irrelevant or injected; that logic is in your thresholds.

If the retriever is down, do not fail open into an LLM with no evidence on a high-stakes action.

Jev retrieval failure errors: implementation notes

Alert on retriever error rate independently from 429s. Cache passage ids so a Jev retry does not require a second search if you do not want one.

Official cookbook: classifying RAG passages. This site is not TypeSafe support.

Symptom → fix

TypeSafe’s public error table lists 401, 422, 429, and 529 only. Channel-specific payment codes you see on other vendors are not a jev.pro IA clone — treat them as callouts in your wrapper.

FAQ

Is “Jev retrieval failure errors” always a TypeSafe HTTP status?

Only 401, 422, 429, and 529 appear in the public API error table. Low confidence, policy block, missing context, retrieval failure, and duplicates are application classes you define.

Should I retry the call?

Retry 429 and 529 with exponential backoff (official SDKs do). Do not retry 401 or 422. Client timeouts may retry in the SDK but can double side effects unless you are idempotent.

Where is the official error table?

The API reference. This page restates it for engineers and maps symptoms to fixes.

What this page does not claim

• Official TypeSafe status, logos, or support.
• That jev.pro sells, issues, or proxies API keys.
• Extra first-party HTTP routes beyond POST /v1/systemone and GET /v1/models unless the API reference lists them.
• Invented latency SLOs, search volume, or unofficial prices. List price and rate limits are vendor claims — confirm on models.
• That a schema-constrained answer is automatically factually correct.
