[BUG] Blank screen on Local Encounter Runner in Active Mode

[alfredocavatelli]

Upon starting an encounter, after adding a single pilot to the default 'Escort' encounter on the dev version of COMP/CON, a blank page opens. Happens every time I've tried to use Active Mode. The pilot is a JSON export of one of my players' sheet from the active version of C/C.
Issue is perfectly reproducible on both mobile and desktop versions of Firefox. I've tried deleting all local data, but the issue persists. Additionally, upon clicking the home button, C/C's homepage appears blank until a shift+F5 refresh is done.

The following error appears in console on the active mode page:

DOMException: String contains an invalid character

Hi, thank you for the report. Two questions:
Does options -> log report anything?
Would it be possible to pass me a copy of the pilot data? You can contact me on Discord at beeftime#0558

[alfredocavatelli]

Sure. This is what logs output in debug. Export log button and copy button aren't functioning so here are screenshots: (note that the trace is for the 'no pilot found' entry)

Will forward pilot JSON on discord.

Hi, this issue persists on the stress test branch of v3. However, log export is fixed so I am including that (log level set to debug). This time around, I created a new LL0 pilot to make sure importing a v2 JSON pilot wasn't the issue.

@alfredocavatelli if you press F12 and go to the application tab, then in the left panel select IndexedDB > COMP/CON Persistent > pilot_sheets, is there any data in the db?

[alfredocavatelli]

Nope, it's empty.

[jarena3]

ok, there's the problem. Your pilots are fine, I think, but your browser isn't letting you save to that db. A few things to check:

• is there any data in any CC persistent db? If not, you haven't given c/c storage permissions, which it'll need to work correctly (you could also save it as a PWA)
• when you create a new active mode pilot sheet, does it throw an error in the console when you click the create button? If so, could you post this error here?

[alfredocavatelli]

PersistentDB is populated, and I've verified that C/C has storage permissions.

Creating an active pilot sheet doesn't throw any errors (log attached).

However! I've noticed that there is a folder in persistentDB called 'pilots' which seems to contain all the data that should be on a pilot sheet. Screenshot:

[jarena3]

that's expected, those are your roster pilots. Let me take a look at this on FF. I've been testing on/building for chrome. I'll update shortly

[jarena3]

turns out it was a FF-only issue due to how it parses part of the generated template HTML. just pushed a build that should be live in 5 minutes and it should work for you correctly after that. Thanks for helping me run this down!
