CosmosDB Trigger is not working with WebJobs

Question

I have CosmosDBTrigger on my 3 WebJobs which is targeting the same container. Meaning, whenever any Upsert happens on this container, these 3 should be triggered. I am seeing the issue where 1 out of 3 job is not triggering and trying to understand why.

I manually disabled these jobs for debug purpose where I hit the break point for WebJob2 and WebJob3. When I do the same for WebJob1 then nothing happens.

This is how CosmosDBTrigger is defined on jobs. If 2 jobs are triggering, then logic seems good to me. Here, WebJob1 is not triggering. What am I missing here?

WebJob1:

public async Task ProcessMessageAsync(
    [CosmosDBTrigger(
      "%Database:DatabaseName%", 
      "%Database:ContainerName%", 
      Connection = CosmosDbConnectionString, 
      CreateLeaseContainerIfNotExists = true, 
      LeaseContainerName = "leases", 
      LeaseContainerPrefix = nameof(WebJob1)
    )]
      string documents, CancellationToken cancellationToken)
{
  // Logic
}

WebJob2:

public async Task ProcessMessageAsync(
    [CosmosDBTrigger(
      "%Database:DatabaseName%", 
      "%Database:ContainerName%", 
      Connection = CosmosDbConnectionString, 
      CreateLeaseContainerIfNotExists = true, 
      LeaseContainerName = "leases", 
      LeaseContainerPrefix = nameof(WebJob2)
    )]
      string documents, CancellationToken cancellationToken)
{
  // Logic
}

WebJob3:

public async Task ProcessMessageAsync(
    [CosmosDBTrigger(
      "%Database:DatabaseName%", 
      "%Database:ContainerName%", 
      Connection = CosmosDbConnectionString, 
      CreateLeaseContainerIfNotExists = true, 
      LeaseContainerName = "leases", 
      LeaseContainerPrefix = nameof(WebJob3)
    )]
      string documents, CancellationToken cancellationToken)
{
  // Logic
}

Answer 1

Theory which fixed this issue: This was due to manually adding or deleting entries in lease container, which corrupted it and caused job's pointer misaligned. Redeployment of the ARM template for cosmos fixed this issue.
