Hi All,

I need to upload 100 images file to Power Pages site. I have tried multiple tools in XrmToolBox. Plugin I have tried:

- Portal Web File Explorer

- Portal - Bulk Web File Uploader

But both of them failed with same error when I try to load the site.

System.ServiceModel.FaultException`1[Microsoft.Xrm.Sdk.OrganizationServiceFault]: The entity with a name = 'adx_website' with namemapping = 'Logical' was not found in the MetadataCache.LazyDynamicMetadataCache with version 83228985 and timestamp xxxxxxxxx (Fault Detail is equal to Exception details:
ErrorCode: 0x80041102
Message: The entity with a name = 'adx_website' with namemapping = 'Logical' was not found in the MetadataCache.LazyDynamicMetadataCache with version 83228985

Is there any known fix I can apply?

Otherwise, is there any other way to upload images in bulk?

You’re running into this error because adx_website is no longer exposed as a Dataverse table in modern Power Pages environments. Microsoft removed several legacy Portal entities from the public metadata surface, and many older XrmToolBox plugins (including Portal Web File Explorer and Bulk Web File Uploader) still rely on those tables.
Because the metadata isn’t available, the tools throw the “entity … adx_website was not found in MetadataCache” error.

Why this happens

Modern Power Pages uses a restricted metadata model

Legacy Portal entities like adx_website, adx_webfile, adx_webpage are hidden

XrmToolBox plugins built for the old Portal framework can’t load the metadata

Result: the tools fail before upload even starts

This is a known limitation, and there’s no fix on the XrmToolBox side unless the plugin authors update their tools (unlikely, since Microsoft has moved away from exposing these tables).

Working alternatives to upload images in bulk

1. Use Power Pages Management API (recommended)

You can automate bulk upload using the Power Pages Web API for Web Files.
This works reliably and supports:

Creating web files

Uploading file content

Setting parent page

Publishing

You can script it using PowerShell, C#, or even a simple Node.js script.

2. Use PAC CLI – Power Pages Upload (supported)

If your images are part of a site structure:

Place them under /web-files/ in your local site folder

Run:

pac powerpages upload

This pushes all web files to the environment in one go.
