Filter processor crashes the collector

[corvaglia-alessio]

Describe the bug
I'm using the lambda layer for instrumenting a python lambda function. Everything works as expected, even using other processors, but when I enable the filter processor, the collector crashes with the following error:

What version did you use?
OpenTelemetry collector v0.54

What config did you use?
The collector config file is the following:

# collector.yaml in the root directory
# Set an environment variable 'OPENTELEMETRY_COLLECTOR_CONFIG_FILE' to
# '/var/task/collector.yaml'

receivers:
  otlp:
    protocols:
      grpc:
      http:

processors:
  filter:
    spans:
      include:
        match_type: strict
        services:
          - my_lambda3
      exclude:
        match_type: strict
        span_names:
          - lambda_function.lambda_handler

exporters:
  logging:
    loglevel: debug
  otlp:
    endpoint: *******
    tls: 
      insecure: true
    headers:
      x-scope-orgid: ******

service:
  pipelines:
    traces:
      receivers: [otlp]
      processors: [filter]
      exporters: [otlp]

I do not know if it is the right repo to open this issue since it is related both to the filter processor and to the lambda layer.

pinging @boostchicken @pmm-sumo as code owners

[boostchicken]

I dont think the spans filter is in 0.54? Only 0.55

Confirmed here in the changelog, please update
