Change version java in Mac:

/usr/libexec/java_home -V
export JAVA_HOME=`/usr/libexec/java_home -v 18.0.2`

Update ID Sequence to latest:

SELECT MAX(id) FROM table_name;
SELECT setval('"table_name_id_seq"', (SELECT MAX(id) FROM table_name)+1);

Sample

SELECT setval('configuration.config_shared_property_id_seq', (SELECT MAX(id) FROM "configuration".config_shared_property)+1);

Update Javac to same version java:

sudo yum install java-17-openjdk-devel
