Item Mapping Migration

I’m finalising our recipes as part of the migration, the last ones we have is to sync data from an external system to an item.

 

In the sentance builder, we had a custom trigger than output a dynamic mapping object and we mapped this to “item mapping”.

in the automation builder, the migration guide says to use “Item Values” now.

 

We have a custom Trigger (“Object Created”) which outputs the custom object definition and a string of the objectId
We also have an Action “Create item from 3rd party” which accepts a boardId, itemValues  and an external object id and then we have  the automation template joining these blocks together.

 

This works fine in the Workflow Builder, it shows the Object from the previous trigger as expected.
 

However it fails in the automation builder. It simply shows “No options available”. If I look at the network requests, I can see it retrieving my custom field defintions, it just doesn’t allow me to map my external data into columns to then process

 

Has any been able to map fields from an external service into monday to create an item via a custom action?

We’ve seen the same issue. We raised a ticket a couple weeks ago, but there is no resolution yet. I’ve noticed the same happen with native monday blocks (trigger and action), so it’s not an issue with the custom blocks. I believe it’s an issue with the automation template. However, it should work in the automation builder through the create from scratch functionality.

Ahh thanks! At least it isn’t just me. I’ll create a ticket as well

Hi, ​@workflowpilot did you get any response back? I tried it today and it seems to not work still and giving “No options available” message.

In previous integration recipe builder there was an option to map the input of the item mapping, but here this too is not available (maybe an issue around here, as I followed the response format as per docs too). Still no luck.
