Error 429- Rate limit is exceeded, Try again after 5 seconds.

The dynamic operation request to API 'sharepointonline' operation 'GetTable' failed with status code '429'. This may indicate invalid input parameters. Error response: { "statusCode": 429, "message": "Rate limit is exceeded. Try again in 22 seconds. Please see https://docs.microsoft.com/azure/logic-apps/handle-throttling-problems-429-errors for more details." }

When you have too many API calls by the flow, the Power automate flow triggers this Error 429.
But i have seen this error exception being thrown, even without say 600 API calls per connection per minute.


When your list structure either has below use cases.

1. Multiple Update Item in the flow.

2. Calling other flows from the same flow.

3. Having branches in the flow, which are either creating or updating sharepoint list.


Fix:

There is no available fix for this apart form change in the design of the flows. 
A user voiced was also raised for this but i see it as declined.

So as of now what we have is reduce the number of Update actions, branches and use conditions.

Creating Nested Galleries in Power Apps. (Parent-Child Relationship)

Image
 This is another most common scenario where in client has two parent child lists or any two lists having a common SharePoint column. And clients wishes to have a relationship on the PowerApps screen where in when he/she selects a particular lets say Program in our example. All the respective Projects following that Projects are shown. In such a scenario we can leverage nested galleries. So what we do in here is we add two galleries on our Power App screen. For Programs gallery the Left one on the screenshot above, we connect it to the Programs list For Second gallery we will connect it to the Projects list. But this is where the magic happens. Here we use Filter () function. So what we do in here is we set the Program's column value in Project's list equal to the Selected Program of left Gallery. i.e. the gallery connected to my Program's list. A more complex version of the same is where you inset the nested gallery inside your parent gallery. In this too everything remains

How to reset a datepicker control in PowerApps?

Image
 Scenario: Simple reset a date picker control. Issue, you can't use normal Reset() function to reset the datepicker control. Solution: Simple create a variable Set(varResetCD, True) and use this variable to update the reset property of DatePicker control. The below Reset() won't work in case of datepicker control We need to create a variable and use it at the Reset property of the datepicker control. Also, if you still see some text inside your date field there are two other places you need to check in one is the datepicker control advanced properties. In the above screenshot all you need to do is clear InputTextPlaceholder. And then select the control and check the DefaultDate property of the date.  This should be set to Today(), you can also change it to something like below If(varResetCD,Blank(),Today()) What this does is sets the control to blank if the variable you have declared above is true.

Reset () function failing to work on Edit form for Combo boxes in Power App.

Image
 Hi Good day, Today we have a very interesting scenario. We have a cascading dropdowns on our Power App screen. The flow for these dropdowns is that a user selects the Division, and a list of Business units containing the selected Division is popped down in your Business Unit dropdown. Now to make it user friendly, we have on change code written on each dropdown. So that if the user decides to change the Division dropdown, the Business Unit dropdown is reset. Please remember in here we are talking in regarding to New Form. On Resetting the above Division combo box, since we have written the Reset function code on Change property of the Division Combo box.   Reset(ddBU);Reset(ddBPI);Reset(ddTeams). The above becomes Up till here everything is hunky dory. This is the classic case of how the Reset() function should behave. But that's not, when you move from new form to Edit form.   The Reset function behaves weirdly. It is able to reset the cascading dropdown values like above. But i
