Trying to validate connector stability before AI-generated ventilation flow: list_flow_trigger_cards fails

Hi,

I’m reposting this because I deleted my previous topic after I accidentally included a Homey identifier in it. :person_facepalming:

Context: I’m currently testing read-only connector stability before using AI to generate a flow for my ventilation system. I am not creating or modifying any flows yet. At this stage I only want to verify that the connector can complete a sequence of read calls reliably in a single session.

What happened:

  • list_homeys succeeded

  • list_flow_trigger_cards failed immediately

Exact error:
flow.trigger.autocomplete.getArgumentValues is missing in manifest

I stopped after that first failure.

Important context:

  • read-only test only

  • no flow creation

  • no flow update

  • no flow deletion

  • no assumptions beyond the live call results

My questions:

  • Is this a known issue?

  • Does this usually point to a broken app manifest or Flow card definition in one installed app?

  • Can one faulty app break list_flow_trigger_cards for the whole Homey session?

  • Has anyone seen this specifically with autocomplete arguments on trigger cards?

I’m mainly trying to understand whether this is a connector stability issue, a Web API issue, or an installed app / manifest issue before I move on to the next stage.

Thanks.
