I am attempting to implement a tail sampling policy to trace only error and latency-based spans. However, I am encountering the following error while trying to implement the same.

`Error: failed to get config: cannot unmarshal the configuration: 1 error(s) decoding:

• error decoding ‘processors’: unknown type: “tail_sampling” for id: “tail_sampling” (valid values: [filter batch memory_limiter attributes resource span probabilistic_sampler])`
