      PipelineCommand::run() in cluster_pipeline_cmd.cpp calls Pipeline::parse() and then Pipeline::optimizePipeline() without resolving the collator and calling Pipeline::injectExpressionContext() in between.

      // Parse and optimize the pipeline specification.
auto pipeline = Pipeline::parse(request.getValue().getPipeline(), mergeCtx);
if (!pipeline.isOK()) {
    return appendCommandStatus(result, pipeline.getStatus());
}
pipeline.getValue()->optimizePipeline();
