Data too long for location field

I'll also mention here that once saved, the Location field just contains a string of numbers and nothing else, although it works fine.

Duh. If the input is set to Leaflet Map, the data formats fine, so ignore that. But otherwise...

Looking further into this, I don't believe it's a storage issue, per se. Here's the error message:

Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'field_location_value' at row 1: INSERT INTO "node__field_location" ("entity_id", "revision_id", "bundle", "delta", "langcode", "field_location_value", "field_location_geo_type", "field_location_lat", "field_location_lon", "field_location_left", "field_location_top", "field_location_right", "field_location_bottom", "field_location_geohash") VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_8, :db_insert_placeholder_9, :db_insert_placeholder_10, :db_insert_placeholder_11, :db_insert_placeholder_12, :db_insert_placeholder_13); Array ( [:db_insert_placeholder_0] => 5 [:db_insert_placeholder_1] => 71 [:db_insert_placeholder_2] => region [:db_insert_placeholder_3] => 0 [:db_insert_placeholder_4] => en [:db_insert_placeholder_5] => 010600000020000000010300000001000000a80300005136e2da961e52c051202a39cd6b4440ea408f649d1e52c0868c12c6e86b4440133e6b56a11e52c03a8ab114f76b44406f847235a31e52c054de79b9f86b4440fb1ef67ba41e52c03e94b43ff96b4440ce8e5e31a61e52c086f4e89ef86b4440e9f78bdcaa1e52c009ff7071...

(This string goes on for pages and pages - no wonder the system refuses to store it.)

Severity	Error

Al the other .json on the site works fine, so I suspected a problem with the data, but the data checks out everywhere. The problem is with [:db_insert_placeholder_5] (location value) as the error message indicates and it's only on this particular region, out of dozens that are working fine.

Any ideas? Suggestions greatly appreciated...

My host (imageleet.com) figured this out:

Storage issue is due to field_location_value column defined as blob in table field_location which limit the data to 64 Kb, If its defined the mediumblob during module installation then large location data can be uploaded if required.

By updating the field storage, up to 64MB can be stored, thus solving the problem:

Storage type update should work for all region as now data up to 64 MB can be uploaded.

Actually the Geofield value field is generated in the MySql Db as a LONGBLOB ...
So I don't think this is a real issue. Could we close this?
