Bad Gateway on Update item action

[TorreyFalconer]

I created a list and used the "build a flow" option from that list. I did that because it gave the trigger option of "When an item in this list is modified", which is not normally an option as a trigger when you build a flow from scratch.

Basically I need my flow to trigger from a modified item, get the item and then update the same item that is in another sharepoint list. I essentially have two separate sharepoint lists that compile into a single other list (master list). When something is deleted from one of the single lists, it needs to then delete from the master list. I planned to do this in two separate flows, as the "modified" trigger will need to be triggered independently from the two lists in order to delete it from the master.

The problem is that I am getting a 502 error on the "Update" action during this flow. I have tried refreshing connections, rebuilding and exiting the browser and nothing seems to fix this.

Hi,

You should not need Get Items, as you already have the item details from the trigger is there a filter on the get items, or are you processing everything in the list everytime one item is modified?

[TorreyFalconer]

One item at a time as it is modified. I eliminated the "Get Items" action and it still gives me the same error.

i would suggest to post the full configuration

In your 2nd list, do the ID's match up?

I suspect not which is why you get th error as there is likely no item with ID 19.

Before the update item do a Get Items the ODATA query will be something like:

Incident_x0020_ID_x0020_Number eq 'ID'

Hi @TorreyFalconer ,

You couldn't enter the ID dynamic content from the trigger in the Id field of Update item action, sice the corresponding item in the master list will not have the same Id with the trigger item.

So please make sure you have a column in the master list would the same with the item in the separate list, such as the Title of the corresponding item are same in the separate list and the master list.

If the Title of the corresponding item are same in the separate list and the master list, you could refer to screenshot below to create the flow:
