invalid execution_time format: %v

Error message

invalid execution_time format: %v

What it means

Thrown in parseFTHybrid (search_commands.go:3131-3138): the optional 'execution_time' field, when present as a string, must be parseable by strconv.ParseFloat. A non-numeric string here trips this error, with the underlying ParseFloat error appended.

Solutions

1. Inspect RawResult() for the execution_time value.
2. Upgrade the server module to a version emitting parseable floats.
3. File a go-redis issue if a legitimate format is rejected.
4. Filter execution_time at the query level if not needed.

res, _, err := client.FTHybridWithArgs(ctx, idx, opts).Result()
if err != nil && strings.Contains(err.Error(), "invalid execution_time format") {
    raw, _ := cmd.RawVal()
    log.Printf("fthybrid execution_time unparseable; raw=%#v", raw)
}

When it happens

Trigger: FHybrid reply where execution_time is a string like 'N/A', 'inf', or empty, so ParseFloat fails.

Common situations: Older/newer module variant formatting execution_time differently, locale-specific decimal separators, or a proxy mangling the value.
