anki.errors.InvalidInput: bug: card modified without updating queue

I get this sort on error each day now (early on in my daily reviews), maybe since upgrading to the v3 scheduler or maybe since upgrading to Anki 2.1.55, I can’t remember sorry.

That’s a different bug to the other reporter, and appears to be an issue with the v3 scheduler. It won’t cause any damage, but I’d like to get to the bottom of it. If you figure out steps to reliably trigger it, please let me know.

[nickw2066]

I haven’t figured out the steps yet.
It seems to happen only once a day, and early on in my daily reviews.
Here are screenshots from my phone from the error today:

Perhaps it relates to the day rollover? If the very first thing you do at the start of a day is to tap on a different deck to the previously selected one (and then the original after that if you wish), which will trigger a queue rebuild, does the error still pop up?

[nickw2066]

Today I tried (on my computer) starting the day by clicking on a different deck, doing a few reviews, then going back to my “All” (container) deck and doing my daily reviews as normal. Sadly the error still popped up:

Each day the error seems to happen at the same place, around the middle of my reviews of the first sub-deck.

[nickw2066]

I seem to have to sync before I can continue the reviews, otherwise the error keeps popping up.

[dae]

I took a copy of your collection yesterday, and today ran a script to run through all the outstanding reviews answering first Again, and then Good, and couldn’t seem to trigger the issue. Are you performing other actions during the review, such as editing cards, suspending/burying any, etc?

I’ll need to tweak the error message to give us more context, so we can get to the bottom of this.

[dae]

Please try again with the latest beta, which will print the card id when the error occurs:

https://betas.ankiweb.net/

If you could then look up the card via cid:<the id> in the browse screen and check its review history, and include a screenshot of the error, that may help to narrow things down. Please also run the following in the debug console to get the time it occurs:

from anki.utils import int_time; pp(int_time())

[nickw2066]

I apologise for my slowness in replying. I have just installed the beta and will follow those steps when the error comes up again. Thank you.

[nickw2066]

The error just happened again.
Here is the screenshot of the error:

I looked up the card with the error printout id via cid in the browse screen:

Notice that this note is different to the error note (it’s Romans 4:19–25; the error note was Romans 4:16–18). The error card is:

Thanks Nick, that was helpful. If my suspicions are correct, turning on burying of new cards in your deck options should stop this problem from happening until we can get a proper fix out.
