Blue-Green deploy stuck on IDLE (invalid route)

I recently opened an incident to SAP, but they are struggling to find it out, maybe you guys could have an idea

When we deployed a Fiori Element app built with CAP in BAS via CICD to CTMS

When I import the MTAR generated via CICD to our target subaccount, the route is stuck with the IDLE in it, and the managed app route can't find that route

if we deploy our app from BAS directly to our target subaccount, then no problem

In CTMS, the deployment strategy on my node is blue-green. I did not have a chance to test it with Default, but my guess is that it will work

Here is an example

The issue names no repository file or test; begin by reproducing the CICD-generated MTAR deployment in CTMS with the blue-green strategy and compare it with direct BAS deployment and the Default strategy. Done means determining why the managed app route cannot find the IDLE route and either correcting the example or recording the confirmed external limitation.
