Small JS error on pipeline with no jobs in Chrome

[bneil]

Currently using the latest via
docker run -d -p 8080:8080 -v $PWD:/data gaiapipeline/gaia:latest

After generating a pipeline (no jobs yet run), i went to the dashboard and got the following error when trying to start pipeline.

index.vue?258e:110 Uncaught TypeError: Cannot read property 'length' of undefined
    at s.checkPipelineArgs (index.vue?258e:110)
    at s.n [as checkPipelineArgs] (vue.runtime.esm.js:190)

    at t (vue.runtime.esm.js:2000)
    at HTMLAnchorElement.e._withTask.e._withTask (vue.runtime.esm.js:1798)

    checkPipelineArgs () {
      // check if this pipeline has args
      for (let x = 0, y = this.pipeline.jobs.length; x < y; x++) { <--
        if (this.pipeline.jobs[x].args && this.pipeline.jobs[x].args.type !== 'vault') {
          // we found args. Redirect user to params view.
          this.$router.push({path: '/pipeline/params', query: { pipelineid: this.pipeline.id }})
          return
        }
      }

      // No args. Just start pipeline.
      this.startPipeline()
    },

this.pipeline.jobs - jobs is currently null which is causing the issue

Hello and welcome @bneil 🤗
Usually you see this error when your pipeline is broken or your pipeline does not expose any jobs.
Gaia executes pipelines as soon as they are build (and detected) and tries to get all jobs. So by defaultthis.pipeline.jobs shouldn't be undefined.

Is there anything in the logs of Gaia? Usually this is more verbose.

Edit: Your pipeline code would also help to reproduce your problem 😄

maybe its because im just using the default golang example?

package main

import (
  "log"

  sdk "github.com/gaia-pipeline/gosdk"
)

// This is one job. Add more if you want.
func DoSomethingAwesome(args sdk.Arguments) error {
  log.Println("This output will be streamed back to gaia and will be displayed in the pipeline logs.")

  // An error occured? Return it back so gaia knows that this job failed.
  return nil
}

func main() {
  jobs := sdk.Jobs{
    sdk.Job{
      Handler:     DoSomethingAwesome,
      Title:       "DoSomethingAwesome",
      Description: "This job does something awesome.",

      // This job depends on something? Define the dependency here with the title of other jobs.
      DependsOn: []string{""},
    },
  }

  // Serve
  if err := sdk.Serve(jobs); err != nil {
    panic(err)
  }
}

which is going to exit in a panic

welp, if i read the error message.... this would of made more sense

panic: job 'DoSomethingAwesome' has dependency '' which is not declared

Sorry about that, closing

[michelvocks]

Thanks a lot @bneil .
My example is actually really bad which I provided. Sorry for that I will fix that!
I will also reopen this issue because we should fix the JS error when jobs is undefined.
