Error message

Cannot find `{LAT_NAME}`, please set it or use JSON or set `{REDIS_VALUE_TYPE}` to `{REDIS_VALUE_TYPE_STRING}`

What it means

A Redis geospatial sink (template encoding, redis_value_type='geospatial') requires the `latitude` option naming the column that holds latitude. RedisSink::validate raises this SinkError::Config when `latitude` is missing, suggesting setting it, using JSON encoding, or switching to the string value type.

Solutions

1. Add `latitude = '<column_name>'` to the sink options
2. Or change redis_value_type to 'string' if GEO semantics are not needed
3. Or use a JSON encoding which does not require this option

Example fix

-- before
... encode template (redis_value_type = 'geospatial', key_format = 'geo::{pk}', longitude = 'lon', member = 'm')
-- after
... encode template (redis_value_type = 'geospatial', key_format = 'geo::{pk}', longitude = 'lon', latitude = 'lat', member = 'm')

-- for redis_value_type='geospatial', verify latitude option present and column exists:
-- options.contains_key("latitude") && schema.contains(options["latitude"])

match result.err() { Some(e) if e.contains("latitude") => add_option("latitude", numeric_column), _ => propagate(result) }

When it happens

Trigger: CREATE SINK with encode template, redis_value_type = 'geospatial', with key_format and longitude set but no `latitude = '<column>'` option (src/connector/src/sink/redis.rs:379-383).

Common situations: GEO sink configs that specify longitude/member but omit latitude; typos like `lat`; assuming longitude alone suffices for GEOADD.
