ErrCodeUserDeprecated

ErrCodeUserDeprecated

Error message

the v1 user API is deprecated; instead, get your user with GET /api/v2/users/me

What it means

The v1 'get my user' endpoint is intentionally deprecated and always returns this error pointing callers to GET /api/v2/users/me. It is an unconditional TypeUnsupported response, not a conditional failure.

Solutions

1. Switch the client to GET /api/v2/users/me (GetMyUser handler)
2. Upgrade the SigLens/last9 client SDK to a version using v2 endpoints
3. Grep your codebase for '/api/v1/users/me' and replace all occurrences

Example fix

// before
resp, _ := http.Get(baseURL + "/api/v1/users/me")
// after
resp, _ := http.Get(baseURL + "/api/v2/users/me")

resp, err := client.Get(baseURL + "/api/v1/users/me")
if err == nil && resp.StatusCode == http.StatusUnsupportedMediaType /* deprecated marker */ {
    resp, err = client.Get(baseURL + "/api/v2/users/me")
}

When it happens

Trigger: Calling GET /api/v1/users/me (the deprecated handler) with any valid auth — it always returns this error.

Common situations: Old SDK/client versions still pinned to v1 endpoints; scripts or integrations written before the v2 migration; copy-pasted curl examples from old docs.
