querying range: %w

Error message

querying range: %w

What it means

After each successful poll, queryRange calls updateURI to compute the next pagination URI from the received timestamps. A failure there (url.Parse failure on the stored URI) is wrapped as 'querying range' and terminates the datasource.

Solutions

1. Fix the DSN URL so it parses as a valid URL
2. Percent-encode special characters in query parameters
3. Test the exact URL with curl before putting it in acquis.yaml

if _, err := url.Parse(dsnURL); err != nil {
    return fmt.Errorf("fix DSN URL before starting datasource: %w", err)
}

if _, err := updateURI(uri, lq, infinite); err != nil {
    log.Errorf("pagination broke after %s: %v", uri, err)
    // restart the polling loop from the base URL instead of exiting
}

When it happens

Trigger: updateURI returns invalid Loki URL (error 464) during pagination — malformed base URI in config propagates through the polling loop.

Common situations: Same root causes as invalid Loki URL: badly formed DSN URL, unencoded special characters.

Understand the failure class

Background: "Invalid URL" errors: why new URL(), URI.parse, and reqwest::Url reject your string — missing scheme, whitespace, and bad path format — this error's family across 39 libraries.
