Azure Cloud Discovery Sensor error

[motsuki17]

When trying to Test Account my Cloud Discovery Schedule, its showing this error:
(See attached image)

There was a hotfix for the script include DiscoverySensor (778011130a0a0b2500c4595ad1d1d768) "System Upgrades: glide-vancouver-07-06-2023__patch7-hotfix2a-04-03-2024_04-09-2024_1017.zip" but it did not fix it. I also tried to repair the Discovery and Service Mapping Patterns v1.12.0 plugin but nothing changed. How to fix this?

Also a warning is also logged in the Discovery Status along with this sensor error:
Warning | Script error in sensor: java.lang.NullPointerException

The ECC Queue queue input state is error, despite the status in the payload is SUCCEED.

I resolved the issue on my own:
Just had to invalidate, then validate the MID Server, then Rekey again and it fixed.

I’ve tried using this solution but no luck

Can anyone provide me the solution for this?

In my case the Sensor was indeed missing. After clicking on Repair for the Pattern Designer plugin this was fixed.

If the Invalidate and Validate steps do not help, you should follow this article

First make sure to check if the Sensor is indeed missing Under Sensors search for "Horizontal Discovery Sensor"

The article above states that you can't Repair the Pattern Designer plugin on your own and must open a ticket to SNOW support. However I was able to "Repair" the plugin and this fixed the issue.
