Azure Function Timer Trigger works for seconds but not minutes

[xzf0587]

I tried to create an azure function for timer. (Using Teams Toolkit extension in VS Code to create a default template app Bot -> Chat Notification Message -> Timer Trigger). And I found it works fine with "schedule": "*/30 * * * * *" but failed to trigger if I update the schedule to schedule": "* */2 * * * *". Any suggestion is welcomed for the problem. Thanks. Here is the bicep for resource deployment.

@maxLength(20)
@minLength(4)

param functionAppSKU string

param identityName string = resourceBaseName
param location string = resourceGroup().location

I got same issue when i use TTK to create project. I set schedule: 0 0 1 *, fired on every morning 1 A.M. , Also not triggered. It did work in local debug session. But when I provision into Azure env, It didn't fire.

Hi @xzf0587 Thanks for reporting will check and update.

Hi @xzf0587 I checked and found its working.locally as well as portal also.can you check it again.

@bhagyshricompany Thanks for your reply. The timer works fine in our old version which uses storage account for Azure function. Recently, we updated the project by using SWA for Azure function and the timer does not work. Does the different storages impact the timer?

Hi @xzf0587 I checked and found its working.locally as well as portal also.can you check it again.

I think you don't enable the RUN_FROM_PACKAGE feature because you don't have this warning bar in the top of the test page.

And here is my test result and snapshot
