Struggling with Google My Business API review aggregation for multi-location businesses, seeing persistent data parsing errors.

hey everyone, i'm hitting a wall trying to implement a solid review aggregation system using the Google My Business API for our multi-location clients. we're consistently seeing parsing failures, seems like malformed JSON or inconsistent schema coming back, which is totally messing up our reputation management efforts. here's a typical error log snippet:

[2023-10-27 10:34:12] ERROR: [REVIEW_AGG_PARSE_FAILURE] Failed to parse review data for location_id: 12345. Malformed JSON or unexpected schema structure. Raw response snippet: {"review_id":"abcde","author":{},"comment":"This is a test.","starRating":"FIVE"}

any advice on robust strategies to handle these GMB API inconsistencies, especially for large-scale reputation management? help a brother out please...
