Automatically collapse long context values

[asherLZR]

Problem Statement

Doing Sentry.setContext('title', { value }), if it goes beyond a certain length, we want value to be collapsed in the UI and not truncated. Otherwise a long array could take up a page of space on the screen. Could we have this configurable as an option to setContext?

hi! just to clarify - you're asking for the ability to collapse/expand the value field in the UI if potentially the value is too long instead of being truncated?

[asherLZR]

Yes exactly. A long value field taking up almost a full page is difficult to read. Ideally it could be collapsed with a preview of the first x number of lines, with the ability to expand it if necessary.

Thanks for the confirmation. This would really be two changes:

1. SDKs would need to not truncate the data before it's sent. Depending on the size of the data, this may or may not be possible. (Generally, that truncation happens to keep both individual context items and the full payload from exceeding the maximum allowable sizes.)

2. We'd need to build partial collapsing into the UI.

We've filed it as a feature request. If we decide to pursue it, we'll let you know!

This sounded familiar, so I searched around and found... an issue I made but was closed due to inactivity! #48480

I think the issue here is not about truncation, since the event still has valid json to display, but that arrays are not being collapsed when they should.

See here for a screenshot of it in action

We won't add collapsing as an SDK option, but we can certainly collapse long array values by default.
