Fix broken user_avatar images during Discourse migration from specifiction.org to discuss.webplatform.org

[renoirb]

While attempting to migrate discourse.specifiction.org into discuss.webplatform.org (ref #152) images of avatars are broken.

Possible causes

Note we didn’t setup asset storage on S3.

1. Internal communication between frontend NGINX server didn’t pass proxy_set_header X-Forwarded-Proto https;? (outcome, it didn’t change anything)

2. Run recommended steps (outcome; read and tried this, this and this , didn’t change anything)

   ./launcher enter app
   rake posts:rebake
   rake uploads:clean_up
   

3. Migrated from specifiction.org to webplatform.org from backup generated from the same Discourse version on both installs? (needs investigation 👍 )

How it looks like

Solution, re-import backup from original that has the same version as new deployment, plus;

./launcher enter app
rake posts:rebake
rake uploads:clean_up

NOTE: didn´t test without it, it was just in case.
