Error message

not implemented

What it means

JSONDebugMemory panics with 'not implemented'. The method exists as a placeholder on the Cmdable surface for JSON.DEBUG MEMORY but has no RESP parsing wired, so calling it always panics.

Solutions

1. Do not call JSONDebugMemory; it is not yet implemented in go-redis.
2. Issue the raw command via client.Do(ctx, "JSON.DEBUG", "MEMORY", key, path) and parse the reply manually if you need it.
3. File/track an upstream issue if you require first-class support.

Example fix

// before
n := client.JSONDebugMemory(ctx, key, "$")

// after
res := client.Do(ctx, "JSON.DEBUG", "MEMORY", key, "$")
bytes, _ := res.Int64()

// Avoid JSONDebugMemory. If memory info is required, use the raw command:
res := client.Do(ctx, "JSON.DEBUG", "MEMORY", key, path)
if err := res.Err(); err != nil { return err }
bytes, _ := res.Int64()

When it happens

Trigger: Calling client.JSONDebugMemory(ctx, key, path) on any client type.

Common situations: Discovering the method via IDE autocomplete or a command catalogue and assuming it works, or migrating from a client that implemented JSON.DEBUG MEMORY.
