alloy's discovery.process block does not export 'targets' field

[computerphilosopher]

Following is part of my config.alloy file

discovery.process "all" {

}

discovery.relabel "agent" {
    targets = discovery.process.all.targets
    // Filter needed processes
    rule {
        source_labels = ["__meta_process_exe"]
        regex = ".*/grafana-agent"
        action = "keep"
    }
}

When alloy started, it says

Apr 24 02:03:23 scratch-front-01 alloy[45086]: Error: /etc/alloy/config.alloy:21:36: field "targets" does not exist
Apr 24 02:03:23 scratch-front-01 alloy[45086]: 20 |  forward_to     = [pyroscope.write.endpoint.receiver]

I followed instruction of grafana agent document I followed the configuration exactly as described in this document. Could there be a difference in the configuration methods between Grafana Agent and Alloy?

No, there are no configuration changes between Grafana Agent Flow and Alloy.

If I'm reading this correctly, the error complains about the export of discovery.relabel.agent, which is output: https://grafana.com/docs/alloy/latest/reference/components/discovery.relabel/#exported-fields

So we'll have to update the documentation, but in the meantime you can change the offending line to discovery.relabel.agent.output and it should work! cc @simonswine

Sorry about the confusion, there has been a mistake, that within the next hour should be fixed: grafana/pyroscope#3248
