DataStore calls fail for dati.comune.messina.it due to compressed/binary response

[aborruso]

Summary

CKAN DataStore calls against https://dati.comune.messina.it fail with a binary/gzip-like payload that our HTTP client doesn't decode, even though the resource has datastore_active=true.

Evidence

• resource_id: 17301b8b-2a5b-425f-80b0-5b75bb1793e9
• resource_show confirms: datastore_active=true
• ckan_datastore_search and ckan_datastore_search_sql both return: "CKAN API returned success=false" with binary/gzip payload.
• Example SQL: SELECT * FROM "17301b8b-2a5b-425f-80b0-5b75bb1793e9" LIMIT 5

Expected

Datastore responses should be decoded and parsed as JSON.

Suspected cause

HTTP client is not handling gzip/br/deflate responses from this portal.

Proposed fix

Ensure response decompression (gzip/br/deflate) before JSON parsing, or set Accept-Encoding/responseType appropriately.

Fixed in v0.4.32 (Workers fetch headers aligned + decompression handling). Release: https://github.com/ondata/ckan-mcp-server/releases/tag/v0.4.32
