Custom Response triggers switch - not working

(2) ShareShare
ReportReport
Posted on by 20
I am creating a flow that is triggered by a form. 
When a form is filled out by a client, it creates a list in Sharepoint. It then sends a 'Custom Response - wait for one response' to a specific member of our team, who selects which level this client should be on. There are three options. Depending on the response, the list created at the start, should then be updated to show the correct level as chosen by our staff member. 
For some reason, the flow fails before it even gets there and I am not sure why it is not getting past it. 
My flow looks like this above.
This is what the "Custom Responses - Wait for one response" Approval request that goes to our team member looks like: (it is currently set as me for testing)
And the Switch variable is on "Approvers Item"
From there, it goes into the different actions depending on the level approved. 
 
But it looks like below when I test it: 
The thing is, it fails on "Update Level on List" before the level is even chosen in the Approval. I am not sure what is wrong with it. This is what it is saying is wrong: 
 
Someone please help me and tell me what is going wrong.

    Hi
     
    I would need to see all the properties etc on the Approval Level Request, because your flow is not simply bypassing it, it is saying it was done successfully, but since there are no responses, you are getting a NULL on the next step
     
    Please review the inputs and configuration of that Approval and Share Here. That's where the problem is
     
    Also though please share whateve is going into the Level action

    Hi FLMike, 
     
    This is what the "Custom Responses - Wait for one response" Approval request that goes to our team member looks like: (it is currently set as me for testing)
     
    From here, it goes to the Switch which I attached a screenshot in the original post. It is On*: Approvers Item, though is currently showing "Current item". 
     
    From there, it goes into the different actions depending on the level approved. 
     
    I am not sure if this helps to answer your question (I am still learning my way around Power Automate),but can provide more if needed. 
     
    Thanks.

    Since you renamed the approval action, I don't know which one you are using. Did you use Create an Approval or Create and Wait for an Approval? Which one you used will make a big difference. If you just used the Create an approval action, you need to follow it with a Wait for an approval. Otherwise, the approval will be sent and the workflow will go to the next action and pass a null value like you are getting. 
     
    When you rename actions, which is a good practice, I would keep the original action name and append it with your descriptive text. For example, Create an approval Confirm level.
