> When i create a dataflow template, the characteristics of Runtime parameters are not persisted in the template file. At runtime, if i try to pass a value for this parameter, i take a 400 error
> I'm using Scio 0.3.2, scala 2.11.11 with apache beam (0.6).
> My parameters are the following :
> {code:java}
> trait MyParameters extends PipelineOptions {
>   def getInput: ValueProvider[String]
>   def setInput(value: ValueProvider[String]): Unit
> }
> {code}
> They are registred with this code
> {code:java}
> val options = PipelineOptionsFactory.fromArgs(cmdlineArgs: _*).withValidation().as[XmlImportJobParameters](classOf[XmlImportJobParameters])
> PipelineOptionsFactory.register(classOf[XmlImportJobParameters])
> implicit val (sc, args) = ContextAndArgs(cmdlineArgs)
> {code}
> To create the template i call sbt with this parameters :
> {code:java}
> run-main jobs.XmlImportJob    --runner=DataflowRunner --project=MyProject  --templateLocation=gs://myBucket/XmlImportTemplate  --tempLocation=gs://myBucket/staging --instance=myInstance
> {code}
> If i pass explicitly --input, it becomes a StaticValue instead of RuntimeValue, and this time, i can see it in the template file.
> The template is called from a google function watching a bucket storage (inspired from https://shinesolutions.com/2017/03/23/triggering-dataflow-pipelines-with-cloud-functions/) :
> {code:java}
> ...
> dataflow.projects.templates.create({
>                 projectId: projectId,
>                 resource: {
>                     parameters: {
>                         input: `gs://${file.bucket}/${file.name}`
>                     },
>                     jobName: jobs[job].name,
>                     gcsPath: 'gs://MyBucket/MyTemplate'
>                 }
>             }
> ...
> {code}
> The 400 error :
> {code:java}
> problem running dataflow template, error was: { Error: (109c1c52dc52fec7): The workflow could not be created.
