Path parameter Swagger definition

Path parameter definition with type array isn't parsed correctly by the Flow UI.
Consider the following definition:
- name: "tag"
in: "path"
required: true
type: "array"
items: {type: string}
collectionFormat: multi


Flow UI is only displaying a single field for petId which makes it impossible to pass in an array.
The end goal is to end up with a path parameter that is something like this ?tag=x1&tag=x2 etc.

The above definition results in allowing you to add "items" for the tag query parameter which is exactly what I'm after. This makes me think that there is no array handling in Flow/Automate UI.

This seems more like a share than an issue, right?🤔

Not sure what do you mean by share.


I have the same problem.
PowerAutomate custom connectors cannot be used in actions, even if you define multiple parameters with the same name.

For example, if you request the following URL with the curl command,
curl -X GET https://xxxxx/api/issues?type=1&type=2


In the Swagger definition:

In the Swagger definition:
       summary: GetIssues
       description: GetIssues
         - name: type
         - in: query
         - type: array
         - collectionFormat: multi
         - items: {type: integer}

After creating a custom connector, issuing a request in a test operation will result in the following:


Instead of escaping [1, 2], we expect

After many emails back and forth, Ms support said it's the way it works and they don't "support explosive arrays".
