In this case, it's because there are many images, and the browserless server is responding "Payload Too Large"

It seems to have been fixed for a long time (browserless/browserless#150), so it should be possible to fix it by incrementing the MAX_PAYLOAD_SIZE env var (defaults to 5mb)

Hey, so it looks like photos are accesable in two places:

1. here, where a pdf is printed using a 3rd party service, which here has had an error due to the total size of the photos
2. A shop dashboard where there is a history of the services of the shop, where there is a camera icon that will download a zip file with all the photos - this should still be working.

So while it looks like we can solve this issue today (to be confirmed) the best practices here is to have these tasks associated with a shop, which also avoids this issue

Struggling the restart browserless with new env var in production because of docker/docker-py#3113

Fixed by increasing MAX_PAYLOAD_SIZE to 20mb
