JSON deserialisation errors when accessing search pages

The number one cause of this is the search engine being out-of-sync with the database, with items being retrieved from search that don't exist or have a different type than those in the graph. If you see validate.error.incorrectType anywhere this is most likely the reason. Try reindexing the type that is being searched.

Links to avatar images are broken

Check you're not using a ModHeader-type browser extension to set the "Authorization" header. Avatar images are stored on AWS which requires an "Authorization" header when requesting files. The EHRI backend also requires an "Authorization" header and the two can conflict if a browser extension is being used to debug either one.
