@01oseluiz are you self-hosting?

No, I'm using the cloud. I was using V2 and recently migrated to V3. I have tested all locally and it works, but on prod I'm stuck. As there isn't any log beside this info "task run heartbeat timeout" I don't know how to debug and fix it.

Sorry, my mistake. I'm using svelte to build e-mails template, so I modify the build to something like that:

//...
build: {
    // config to build svelte files
    conditions: ['svelte', 'browser'],
    external: ['svelte-preprocess'],
    extensions: [
      syncVercelEnvVars(),

      esbuildPlugin(
        esbuildSvelte({
          preprocess: sveltePreprocess(),
          compilerOptions: {
            generate: 'ssr',
            discloseVersion: false, // disable runtime dependency on svelte
            dev: false,
            hydratable: false
          }
        })
      )
    ]
  }
//...

the conditions statement causes the error. I was thinking that this statement would be additive and not overriding
