Error transacting db.type/bigdec

[sg-qwt]

Seems very similar to #88, jdk 17, using datalevin as normal library

(def conn (d/get-conn "testdb" 
             {:name {:db/valueType :db.type/string}
             :height {:db/valueType :db.type/bigdec}}))
(d/transact! conn [{:name "John" :height 123M} {:name "Peter" :height 12M}])

Execution error (ExceptionInfo) at datalevin.scan/get-first (scan.cljc:233). Fail to get-first: "Value out of range for byte: -255"
