Q: No preview/diff button

[jtagcat]

I have 2 watches with no Preview or Diff button. One of them returns just HTTP plaintext, and other one is duplicated from Github GraphQL API (same URL). I have 3 watches of GH GQL API in total, 2 other ones work just fine.

The watches with no Preview or Diff seem to be updating without errors, but I'm actually unsure if they actually get any content (or empty?)

please attach your backup zip, i cant do anything without that information i think

Created a new instance, and added 2 watches:

• Tailscale · GitHub
• copied ^, named it to Tailscale2; removed the JSON filter (to cause a Diff)

Neither had a Preview button. The first one doesn't still have a 'Preview' button.

2 other ones work just fine.
Was probably due to me experimenting with filters before (causing a Diff).

Unfortunately, I can't include the second example, the HTTP plaintext one.

history is empty, so theres nothing to preview

can you try this branch? you should see errors in your 'watch overview' if something happens

[jtagcat]

readding / creating a copy works — issue solved, but already-existing watches without a preview (at first revision) don't get a preview on recheck.

without a preview (at first revision) don't get a preview on recheck.

I dont understand

so on the keep-worker-errors-as-watch-notice branch it works
but on the master it does not?

[jtagcat]

The bug does occurs on master, does not on keep-worker-errors-as-watch-notice

..but if you start a new instance on master, and upgrade to keep-worker-errors-as-watch-notice, you have to copy or remove+readd watches for it to take effect.
