[BUG] Four policies for single action don't work

Type of Connector

Independent Publisher Connector

Name of Connector

TP-Link Cloud (Not yet submitted)

Describe the bug

For this API to be set, it requires two policies to be set:

1. Route all requests to the base URL:
   

2. Set a property for each action within the POST body for the action method:
   

This correctly works, with the authentication action correctly returning a token:

To submit this as an IndiePub, I'm like to use a set connectionParameters for the username and password also required as part of the authentication action. I've downloaded the connector and added the following to apiProperties.json:

then uploaded the changes back. I then add the two policies:

but when I test it, it doesn't take the username/password. I've tried creating new connections and testing it in a new Flow, but it is not working.

Is it possible that four policies are too many? I don't see anything in the documentation saying there is a limit.

Is this a security bug?

No, this is not a security bug

What is the severity of this bug?

Severity 2 - One or more important connector features are down

To Reproduce

Create custom connector and add four policies for one action.

Expected behavior

connectionParameters should be used

Environment summary

Power Automate Editor

Additional context

Can't submit if not working.

Start in the Power Automate Editor with the TP-Link Cloud custom connector and review the apiProperties.json connectionParameters alongside the four policies configured for one action. Reproduce the authentication flow with newly created connections and verify whether the username and password are used; done means the connectionParameters are applied and the connector can be submitted.
