Hello @naruk89179065 

If I am not mistaken, the error doesn't convey any issue with your code

It has encountered an error while checking the status of publish queues. Please try following:

• Go to Tools > Distribution
• Check the replication queues, if any of them are blocked.
  • Is it a content?
  • Is it something deployed via code? 
• If yes, please check why are they failing and resolve the issue
• Delete the item from the queue thats blocking the queue
• Deploy again.

There was also a recording shared few days ago regarding deployment failures. Please check if it helps

thanks @aanchal-sikka 

I verified and didn't find any replication queues block in the server, did a servlet modification sling. servlet.resourceTypes=" + "sling/servlet/default",  replaced by resource component path ,
Able to deploy code successfully in the server.

I am able to fetch data in my local instance,it's working fine 
When  tried dev server  its throwing below error

@naruk89179065 

The indexes seem to have issue. 

Please raise an Adobe ticket

[naruk89179065]

thanks @aanchal-sikka 
 I wrote custom node iteration code ,then its working fine

Thanks
Kotireddy

@naruk89179065 

Thats interesting. 

"Checkpoint r18ab39310ce-0-4 doesn't exist. Debug info:_Mount: [default]_Checkpoints:_ -" fixed by node iteration?

I might be absolutely wrong, but curious. The 2 logs shared seem unrelated to resolutions. 

Can you please verify the logs again, you might still be getting these errors. If not, then its really good to know.

Thanks for sharing the info on the thread
