Hello,
I am trying to create a new trigger on a free tier cluster. The trigger is of database type and at the collection level. However, when I attempt to set the cluster, I do not see any options available.
As you can see on this screenshot
Thanks
Hi @Juanjo_Martin_Cara and welcome to the MongoDB Forums!
Just tried it on an AWS, free tier M0 cluster and I’m able to select my cluster. I just went through these two screens:
And then:
Can you try to create a new project in your organization, then create a new free cluster in a different cloud provider / region to find the root cause of the error?
Again, welcome to the MongoDB community and hope this helps!
Hi @Juanjo_Martin_Cara ,
This is usually because there’s no Data Source linked to the application that contains the Trigger: there’s a Linked Data Sources menu item on the left, ensure that the page contains a reference (Service Name) to the Cluster you want to work with.
This is it! The data source was not selected.
I find it a bit unintuitive that this option is literally the last one in the list but I added my cluster there and solved the issue.
Thanks!
