Scheduled Plugin Updates: Unable to schedule through /plugins/scheduled-updates/create flow

[alexapeduzzi]

Context and steps to reproduce

Here's a video showing the issue.

When I go to https://wordpress.com/plugins/scheduled-updates/create, I'm unable to create a new schedule, even though I have two plugins installed (Gravatar Enhanced
and WP Recipe Maker) that aren't managed by WordPress.com.

When I go to https://wordpress.com/plugins/scheduled-updates/howdywordcamp.com, I am able to create a schedule with plugins that aren't managed by WordPress.com.

To reproduce:

1. Install and activate non-WordPress.com-managed plugins (example: https://wordpress.com/plugins/wp-recipe-maker/).
2. Go to https://wordpress.com/plugins/scheduled-updates/create and try to create a schedule to update that plugin (I wasn't able to).
3. Go to https://wordpress.com/plugins/scheduled-updates/YOURURLHERE and try to create a schedule to update that plugin (I was able to).

Site owner impact

Fewer than 20% of the total website/platform users

Severity

Moderate

What other impact(s) does this issue have?

Agency or developer revenue

If a workaround is available, please outline it here.

It looks like the https://wordpress.com/plugins/scheduled-updates/YOURURLHERE schedule maker does work, so that would be a workaround for the https://wordpress.com/plugins/scheduled-updates/create flow.

That said, we're trying to show off our "one dashboard" for managing sites in a WordCamp promo video, and some of the bugs in the /plugins area (this one and this related one) are making that difficult.

📌 FINDINGS/SCREENSHOTS/VIDEO
I tried this with a site that didn't have "un-managed" plugins, and after installing a few, I was still not able to schedule plugin updates from https://wordpress.com/plugins/scheduled-updates/create, but I could from https://wordpress.com/plugins/scheduled-updates/create/__SITE_ADDRESS__

I've assigned it to @Automattic/nexus since we worked on this previously.

Thank you @ouikhuan !

I reproduced the same issue on production, but the local and wpcalypso environments look fine. I thought it was related to caching, so I cleared the calyso_store index db. That fixed the state, and the plugins were appropriately loaded.

My next step is to test the plugin loads logic locally and determine what could cause the issue.

I can not reproduce it. It happens randomly from time to time; there is no pattern.
I am almost sure that it’s related to query result caching. Next time I stumble upon it locally, I’ll provide a fix. I decided to leave it for now since it rarely happens, but I'll keep my eyes open.
