Some Icons disappeared

[Lucinda_Mason]

This started last night. I haven’t changed anything related to the icons. All icons, the ones missing and the ones that show, are ones found on AppSheet servers. When I follow the url from the data source, they appear, just not in the app.

Any clue as to why they aren’t showing? Thanks

Maybe its related to this setting, try to turn it OFF.

Heru,

I did have that ON but it’s weird that it only affected some of the icons.

The only ones that DISAPPEARED were with the size in the URL like this:

This url works: https://www.appsheet.com/content/img/appicons/education-training.png

So it is working since I changed all the URLs to the short version but the other version had worked perfectly until last night. Did something change with AppSheet? I did see this morning that I now have the ability to choose a custom theme color so maybe it is related to that roll out?

For manual constructed URL it relates to this issue below, for URL that was obtained by uploading an image to AppSheet it will work like what you’ve said. Detail is here:

Call to Action for Apps Constructing URLs to GetTableFileUrl Announcements

We recently made a security enhancement wherein image and file type columns have signed URLs generated for them. This enhancement prevents an app user from changing the table name or file name parameters in order to access app files that they should not. In the near future, we are going to start requiring calls to the gettablefileurl and getappfileurl endpoints to have valid signatures. What does this mean for you? If you have an app where you are manually constructing a link to a gettablefileu…

This doesn’t look to me like it’s related to gettablefileurl or the security setting for signing image and file URLs at all since the URLs in question don’t go to gettablefileurl. I think this might have to do with a recent change made to the /remote endpoint. @Adam do you know why this might be happening?

What does “/remote endpoint” mean?

[hugheshilton · Accepted solution]

Take a look at the screenshot of the spreadsheet in the first post. Notice that some of those image rows start with https://www.appsheet.com/remote/ with an encoded URL coming after that.

The purpose of /remote is to resize images. So if someone adds an image to their app with a full URL to an external location, we will send that image through the resizer so that the app loads faster. That behavior happens automatically within AppSheet. In this case though the URL already has remote in it so the image is actually being passed through remote twice which I guess could cause a problem.

The reason that there have been problems with this recently is that previously we couldn’t handle https links in the remote resizer. Now we can so there was a change a few days ago that caused more links that previously would not have gone through the resizer to start using it.

Thanks for the explanation.
