Release v0.3.6 broke the API because it upgraded the stac-fastapi.pgstac dependency from 2.5.0 to 3.0.1 without removing the Context extension, which is no longer supported as of stac-fastapi v3.0.0.

Fixed by another release: #694

The resolution was just to remove context from the list of enabled extensions. It seems that the context field still appears in our API responses, e.g. https://stac.asf.alaska.edu/collections/sentinel-1-global-coherence/items:

  "context": {
    "limit": 10,
    "returned": 10
  }

Although, the current stac-fastapi Changelog includes the following under "Unreleased":

Remove deprecated context property in types.stac.ItemCollection model

So maybe that field will go away soon.

Note that according to stac-utils/stac-pydantic#138 and radiantearth/stac-api-spec#396, the context functionality has been replaced by numberMatched and numberReturned from OGC API, though I haven't found an example query to confirm whether those fields appear in our API responses.

In any case, I think we can consider this fixed unless more problems surface.

Also note that we did try to downgrade stac-fastapi.pgstac back to 2.5.0 as a quick fix, which also required downgrading pypgstac[psycopg] from 0.8.6 to 0.7.10, but our make configure-database command failed with Could not determine path to get from 0.8.6 to 0.7.10 during the CodeBuild run, so it's worth keeping in mind from now on that reverting an already-deployed pypgstac[psycopg] upgrade is not an easy process.
