org.postgresql.util.PSQLException: ERROR: syntax error at or near "(" when calling org.postgresql.jdbc.PgPreparedStatement.getParameterMetaData - Mailing list pgsql-jdbc

We are using Postgres 14.4 server and 42.5.2 of org.postgresql:postgresql to connect to it from Java.

We get following exception:

Caused by: org.postgresql.util.PSQLException: ERROR: syntax error at or near "("
  Position: 13

at cdao.dpde.InsertHelper.setParameters(InsertHelper.java:53)

where the code in the last line is:

ParameterMetaData parameterMetaData = query.getParameterMetaData();

How can we fix this?
