Power Automate Custom Connectors on copied environments

[DejWass]

Hi guys,
I did a copy of customers UAT environment and testing new functionality here. I´ve created some flows and currently I am trying to make them working.
I have 3 new flows and 2 of them are using our custom connector for Word document generation.
I have problems with these 2. I am able to add new connection while importing.
When I open those flow I got this:

If I leave it like that I am able to open steps using TALXIS_Connectors_Word but actions are broken:

If I create a new connection like this:

I get same error:

Previously trying to make it work I deleted apiId from flow definition because this way it is done on other projects

Anyway...I found out that the invalid connection error can be fixed like this: https://manueltgomes.com/microsoft/powerautomate/power-automate-invalid-connection/

So I tried to replicate this but my flows are not showing any connections:

And after clicking on connections it prompts me to start trial:

So I checked licenses on client PROD environment when we are using another flow with our custom connector and:


Same issue on PROD with another flow.

And after clicking on connection references I get same pop up about starting a trial.

So the questions are:
Is it possible that after changing the MS licensing you need to buy some extra pass to work with custom connectors in flows?
Am I just doing something wrong?
How to fix this? Just buy some passes? And are there passes assigned automatically?

Afaik environment copy lifecycle operation breaks custom connectors. Does it work when you create a new flow?

The invalid connection blog post is not related to this since here you have a problem in the connector not connection.

The licensing prompt is just a bug in the editor. This issue is not licensing related. Please change the title.

It is a known limitation of custom connectors @DejWass
