"no workflow" instead of the expected workflow

Build Environment
1

I am no expert on CircleCI or the config.yml that we are using, as we have had third-party devs to set this up for us (and yes, I have asked them also about why the behaviour is as described below).

The first thing that struck me as odd is the message, that is only visible if I show “All pipelines”:

Could not find a usable config.yml, you may have revoked the CircleCI OAuth app. Please sign out of CircleCI and log back in with your VCS before triggering a new pipeline.

Then, when I via CircleCI website use the “Trigger pipeline” (and I dont add any parameters/properties), I get a new row for the pipeline, but it says “No workflow”.
only get a valid workflow if I do the following:

  • Trigger Pipeline
  • Add Parameters → “only_build” set to true (if set to false => “No workflow”)

I am pasint the config.yml here, in the hope that someone might spot something.

What you have there is a master class in how to use YAML to drive the circleci build process, but that will limit the number of people who can understand the code you have posted. This is then complicated by the amount of understanding of circleci that the developer has… To be honest, I’m looking at the script and mainly saying to myself that’s cool or can I really do that?

You need to ask the original developer about how “<<: *tag_filters” is being used within all the “workflow/jobs” as this adds a filter to cause actions to only take place when a tag is added, but from your description of the steps you are taking you are not using tags.

Masterclass eh. That is a good mark, I guess. But yes, I have asked the dev to figure it out for me, but I wanted to ask the community if they could see what is going on also, since we might not have this dev any longer.
