That function then ranges over `tagSet.Tags`, which panics. Separately, `Create` calls `tagCreate(ctx, data, resp.Diagnostics, r.Client)` and discards the return value. `diag.Diagnostics` is a slice passed by value, so errors that `tagCreate` adds never reach `resp.Diagnostics`. That means **no** tag create error is ever reported, crash or not.
