Power Pages - multistep form file upload size-related error

Posted on by jfitzpatrick

Hello,

I have a Power Pages site with a multistep form that acquires some information from users. The final two steps of the form have users upload files (using the File column type as the only fields on those steps). When a file is submitted that is larger than 115KB, there is an error.

I've tested the Dataverse database/fields in Power Apps, and any file submission less than the 10MB limit is successful, so I don't think it can be a database issue. Each of the File-type fields has the "Maximum File Size" property set at the maximum, 131072KB. Running a network trace during the submission attempt returns a 403 error, although I'm not sure what permission error could be occurring - all users have all permissions necessary for this. This error has only occurred with the Production site in the Production Environment. When testing the Development site in the Dev Environment, there have been no issues.

Has anyone experienced a similar issue regarding File submissions? Is there a way to fix this, or at least determine the cause? If any additional information is needed, please let me know.

Any advice is greatly appreciated. Thanks!

Hi @jfitzpatrick,

I think that is the setting of the field itself rather than the settings on the portal, eventhough you configure it in the power pages editor.

Your probably have to write some custom Liquid to achieve what you need.

Hi @domliu

I found the "Maximum File Size" property under the advanced options when I create/edit a column in the Power Pages data section. The limit to when an error occurs seems to be 115KB whether I have the property set at the default 32,768KB or the maximum 131,072KB.

Hi @jfitzpatrick ,

Where did you see the "Maximum File Size" property for the file field?

I have a note attachment metadata that has the exact same property, i set to 20000kb and it works fine for me.
Test upload over 20mb

Cheers,
Dom
