Custom File column not appearing in Dataverse “Update a row” action

Hi all,

I’ve run into a blocker using Power Automate + Dataverse in a solution-aware flow. My scenario:

Solution: Invoice Processing
Table: Invoice Task Test
Custom column: Invoice PDF (Data type = File)
Flow: created under Solutions → Invoice Processing → + New → Cloud flow
Trigger: When a new email arrives in a shared mailbox (V2)
Step 1: Add a new row (Table: Invoice Task Test)
Step 2: Update a row (Table: Invoice Task Test, Row ID ← Invoice Task Test (Primary Key) from Step

Everything works except: when I expand Show advanced options in my Update a row action, I only see the standard activity fields (Subject, Description, Due Date, etc.) my Invoice PDF file column never appears, so I can’t map the attachment’s ContentBytes, file name or contentType. I’ve:

Saved the flow and reloaded the designer
Published all customizations for my solution

Questions:

What am I missing to force Power Automate to load my custom File-type column under “Update a row”?
Is there an additional step (re-publish, refresh metadata, version requirement) to make file columns show up?
Has anyone run into this and can share the exact connector/action setup that worked for them?

Thanks in advance!

Hi @CU09051456-0

Is there any chance, its the wrong environment on either side?

Are you using Environment Variables or hard coding the table?

I will probably suggest things you did but

1. Save and close the flow

2. go to your solution and save and close it

3. Go to the Solutions Screen, and Publish all customizations from there (not your solution)

4. Load your Solution and verify that you see your table and the new field

5. Create a new Manual Instance flow and add an action to look at that table and see if you see the Field

If you do, good, trash that flow

6. Open your old flow. Trash the Action and readd it

It should show up.

Hi @Michael E. Gernaey,

Apparently there is a different action I need to use to upload a file which is this:
