Displays wrong photo about iznik-nuxt HOT 6 CLOSED

from iznik-nuxt.

The previous post was #79418930. There were no draft posts.
The correct image eventually showed on the front page, but the lag is very confusing for the user.
What's worse is that initially an image was shown from another of my posts which was for something completely different.

@ChrisOfBristol when you say "on the front page", which specific URL do you mean?

Notes to self.

API logs show that the second message was created with two photos:

{"call":"message","collection":"Draft","locationid":8031243,"messagetype":"Offer","item":"Samsung Colour Laser Printer","textbody":"Samsung CLP-315 colour laser printer\n\nPrints are very blurry at the moment as it has been sitting around getting dusty, hopefully it will clear if you run through several black and white pages. \n\nNo wireless. Includes mains and USB leads. Width 385mm, height 245mm, depth 310mm and tray sticks out the front a further 55mm. I will email the manual and the drivers are available online. \n\nPrompt collectors will be preferred.","availablenow":1,"attachments":[19788755,20383322],"groupid":253538,"email":"XXX","modtools":false,"type":"PUT"}

19788755 no longer exists but probably dates from around the start of May, so it's definitely an old photo. Images are cached in local storage indexed by message id; for unsubmitted messages these are -1, -2 etc. to avoid linking images to the wrong message.

Web server logs show a fetch of that old photo from the /give page at 08/Jun/2021:15:06:28 UTC, shortly before the post of the next photo at 2021-06-08 15:10:47, and submission of the second message at 2021-06-08 15:10:47.

That's what I'd expect if it was loading an old draft post in, and then Chris went on two add a second photo and complete the submission. That's not what Chris recalls, obviously.

We don't have backups or web logs from the time the original photo was created; the oldest is 12th May. I've restored that, and it doesn't shed any light on the older post.

@ChrisOfBristol I've investigated this as much I as I can. It's consistent with an old draft stored on the client side with a photo in it, and then you not noticing that and going on to add another photo and post it. I'm aware that wasn't what you remember, so apologies if it's annoying to suggest that. There isn't much more debugging I can do on this one, I'm afraid.
