v2.0.0-alpha.32 Could not load image from tile server about mapillary

[tsmock]

I'm copying my response from JOSM #21260 below:

2021-08-27 19:07:47.144 INFO: GET https://tiles.mapillary.com/maps/vtp/mly1_computed_public/2/{z}/{x}/{y}?access_token=MLY|4223665974375089|d62822dd792b6a823d0794ef26450398 -> HTTP/1.1 404 (546 ms)

This is actually JOSM checking to see if the URL returns a json file (i.e., if it has styling). This is not the root cause.

I took a look at the area in both the Mapillary plugin and the Mapillary website:

• https://www.mapillary.com/app/?lat=52.316078574972096&lng=13.719683684608185&z=15.540691298997581

(This came from the tile in a url in the report, 14/8816/5388)

The reason why nothing is showing up is that the vector tiles don't currently have anything in them. If you have recently uploaded something, please wait a few days ''after seeing that they have been processed'' before getting worried over the images not appearing. Based off of past experience on this, it seems that there are two steps:

1. Image injestion finishes on Mapillary's servers (this is when the email was sent out, or at least it was a month or two ago)
2. Regeneration of vector tiles. This seems to happen a few days after (1) finishes. I don't know what the exact schedule on this is, but a week should be ''more'' than enough time.

Reason was found: JOSM was set to a different projection than Mercator.
While tiles from mapillary were received, the reprojection does not work.
