Actions on multiple projects do not work for more than 15

[SusanRatiLane]

Describe the bug

Forum comment; https://community.appinventor.mit.edu/t/new-app-inventor-user-interface-in-open-beta/121516/

"A while ago I was struggling to export aia projects if I just clicked the select all checkbox, or selected +20 projects. By trial and error I found that selecting @ 15 projects exported OK, therefore each month, when I have a clear out, I select no more than 15 at a time, and this works OK.

Similarly, trying to delete more than 15 projects at one time from trash generates an error, and fails. Again, by only selecting 15 projects I am able to delete without error."

Affects

• Designer
• Blocks editor
• Projects Explorer
• Companion
• Compiled apps
• Buildserver
• Debugging
• Other... (please describe)

Expected behavior

Any number of selected projects should move to trash or delete, including when "Select All" is checked.

Hello, @SusanRatiLane I tried replicating the issue mentioned, but I couldn’t reproduce it on my local setup. Here are the details of my testing:

Exporting AIA Projects:

I selected more than 15 projects (using the "Name" checkbox and manual selection) and successfully exported them without encountering any errors.
Both bulk exports and individual exports worked as expected.
Deleting Projects from Trash:

I tested deleting more than 15 projects from the trash, and it worked fine without any errors.
Both the "Name" option and manual selection for deletion behaved correctly.

This is interesting. It's possible an update fixed this problem without us realizing it. I'll investigate.

It will only happen in production. App Engine limits runtime to 1 minute and once a job hits that limit the connection is terminated. You won't see this behavior in the dev server. Supposedly when we moved to Java 11 that was meant to increase to 10 minutes in the docs but I haven't looked recently.
