Map Viewer and Uploading Documents

NathanGabbard — Mon, 29 Jun 2026 16:25:20 GMT

Good morning,

Just wanted to see if anyone else is running into issues with uploading PDF's or any document at all to their layers in Map Viewer. I've tried pdf, jpg, xls, and a few others and I always get This file type is not supported. All of them are well under the 10 mb limit.

I have numerous documents uploaded on the layer already, so it has worked in the past.

I am also unable to access any attachments in a layer in Map Viewer. In contrast, before the update on Friday, I could see and edit (add or remove) any attachment associated with any collected point.

Thanks for the confirmation. This update seems to have been a doozy! Not being able to upload documents is a serious issue though...

@NathanGabbard @Teri_Dane can you invite "craig_sp" user to a group that has access to the data?

That will allow us test this out.

For what it's worth, I just tried testing this on one of my hosted feature layers and I was able to successfully attach both a JPG and PDF file....

Are you still experiencing the issue today?

If so, definitely worth opening a support case with Esri to get it logged as a potential bug

Hi @Katie_Clark , out of curiosity have you made any changes to the form (using the new attachment element) on this layer? Or have there been no form changes

Re: Map Viewer and Uploading Documents

Katie_Clark — Mon, 29 Jun 2026 19:08:01 GMT

No I didn't make any changes, just using the default form. I was testing on this layer, editing within this Map Viewer edit interface (screenshot shows a second attempt where I successfully added a word doc)

@NathanGabbard and @Teri_Dane. I am unable to reproduce this behavior. Can you try to clear your cache on the browser, reload and then upload a document attachment that was failing? If the issue still persists, please invite the "craig_sp" user to a group that has access to the data like @CraigGillgrass mentioned so we can see what's going on

Hi BBollin,

I just added Craig to the group for access. My co-worker in the Planning department was the one who notified me. It seems to be not just my computer/browser.

Hi @Katie_Clark,
Yes, I am still experiencing this today. I am unable to view/edit (add or delete) attachments in either Map Viewer or Experience Builder based on a map with the same layer.

So dragging and dropping I get the file type error however when I select it through windows file explorer, I do get to show up here:

However, it still doesn't upload when I go to the pop-up. Maybe I'm just having a brain fog Monday but yeah, can't seem to get it to show up.

@NathanGabbard I'll need steps to reproduce this with the map you sent me, please see the DM I sent.

The solution that ended up working for me is deleting the map and restoring it. Not sure why that worked but it did.

Thanks everyone for looking into it though, much appreciated!

@NathanGabbard we've tracked down the issue you were seeing. There's a bug in Map Viewer, where Drag and Drop for Attachments in the form is not working. Using the file browser, i.e. clicking Add File, should work for you and I believe it does.

We're evaluating if we can address the Drag and Drop issue for Attachments in Map Viewer for this release.

Yeah that was one other issue we noticed as well. The drag and drop used to work but no longer does. Glad you guys are looking into it!
