Fix Power Apps Camera Images Not Saving as SharePoint Attachments
Question details
Users encounter a "Field ID is required" network error when attempting to save images captured via the Camera2 control in Power Apps to a SharePoint list attachment field using the Patch function.
- Product
- Power Apps
- Device & OS
- not provided
- Scenario
- Developing an inspection app in Power Apps that captures camera images and saves them as attachments directly to a connected SharePoint list.
- Observed behavior
- The captured images fail to appear in the app's attachment control or the SharePoint list, and a "Network error when using Patch function: Field ID is required" message is displayed.
Ensure that your target SharePoint list has the attachments feature enabled in its advanced settings, as Power Apps cannot push files to a list that does not accept them.
Verify Attachment Control Schema and Form Data
Ensure the image collection schema matches the exact structure expected by the Power Apps attachment control and SharePoint list.
The "Field ID is required" error typically occurs because the collection being passed into the Patch function does not contain the mandatory properties that SharePoint expects for an attachment item. The attachment control requires specific fields like Name, Value, and ID to successfully bind the data.
Navigate to your SharePoint list, click the gear icon to access List Settings, open Advanced Settings, and confirm that 'Attachments to list items' is enabled.
Inspect the formula generating your collection from the Camera2 control. Ensure each record explicitly includes DisplayName (or Name), Id, and Value fields.
If you are creating a new record, ensure the ID field in your attachment collection is either omitted or passed as an empty string, as SharePoint assigns the ID only after the parent item is created.

Frequently Asked Questions
Why does Power Apps require a Field ID for SharePoint attachments?
Power Apps requires a valid Field ID to map the uploaded image or file to the specific underlying SharePoint list item schema. Without this mapping, SharePoint cannot associate the attachment with the correct record.
Can I save Power Apps camera images directly to a document library instead?
Yes. Instead of patching an image as a list attachment, many developers use Power Automate to capture the image's Base64 content from Power Apps and create a new file directly in a SharePoint Document Library, which often bypasses attachment schema errors.
How do I check if my SharePoint list accepts attachments?
Go to your SharePoint list, click the gear icon to open List settings, select Advanced settings, and verify that the 'Attachments to list items' option is set to Enabled.
