Flows failing, fails to update item and possible throttling

All, I am new to flow and to sharepont fyi. 

I created a flow that generates an approval email that is sent to three people whenever an item is added to a certain sharepoint list. The user can accept or reject, then it updates a column to say "approved" or "rejected" (there are 3 columns, one for each user). If one user rejects, or all 3 approve then it sends an email to the creator of the item that the approval is accepted or rejected.

The issue is that it is not always updating the column to say "approved" so we don't know it has actually been signed, I know this because the column is left blank but the final email does send meaning all three people did approve it. 

Digging in to the flow I have some failures I think are related: image.png

I found this article here on throttling and it sounds related, it also references the 429 error. This is as far as I have gotten. 

#1 This is a corporate set up, would this be an internal server or a microsoft server?

#2 HELP

Hi TysonAi,

 

Error 429 means that too many calls are going out from Flow to the Office 365 connector and you are hitting the limit on it. Please reduce the number of calls being made by your flow.


The Internal server error comes from the connector but not Flow.


About our scenario, please consider to add a parallel branch in your flow.


Please check this blog for more details about parallel branch:
https://flow.microsoft.com/en-us/blog/parallel-actions/


Then you may consider to configure your flow likes below.


Please take it for a reference.

Re: Flows failing, fails to update item and possible throttling

Thank you for the response. I am not sure why there are an excessive amount of calls being made, this flow is only ran maybe 10 times daily at max. 

Could you explain more what is happening and why parrallel flows help? As well as give me more detail on how to set up the parrellel flows to fix my issue? What information do you need from me to be able to do so?

Thanks!

Hi TysonAi,

 

About error 429, I have reported it on my side. I will back to you once I got any updates.

 

Considering that you have three columns in the list for each approver to update corresponding response, so I add a parallel branch in the flow so that I can get each approver’s response without conflict. And I assume that you won’t get the 429 error code when using the start an approval action. It’s a workaround I am considering. Please have a try with it, I guess it should work for you.

@TysonAi - did you get a chance to apply @v-yamao-msft's suggestions to adapt your Flow?

 

If yes and you found that solution satisfactory, please go ahead and mark this thread as "Solved". Smiley Happy

 

Happy Flowing,
