Bitbucket Server pages are not loading successfully and the server returns the 500 http status.

The following appears in the atlassian-bitbucket.log:

Caused by: java.lang.RuntimeException: Could not get unique fields for table 'AO_92D5D5_USER_NOTIFICATION'

Note: the table may differ in your logs depending on the add ons installed in your instance. However, the table name will always be starting with "AO".


PostgreSQL 9.6+.


The support for PostgreSQL 9.6+ has been introduced as part of version 4.11.0 (see  BSERV-9225 - Getting issue details... STATUS ).


Option #1 - Upgrade to the latest Bitbucket Server version (recommended)

The recommended solution for this problem is to upgrade to the latest Bitbucket Server version.

PostgreSQL 9.6 is supported since Bitbucket Server version 4.11.0.


Options #2 - install the postgresql-9.4.1211 jar

In case an upgrade is not possible, follow the instructions below to use a more recent postgresql jar.

  • Stop Bitbucket Server
  • Locate the jdbc driver for PostgreSQL

    • The file will be located in the <Bitbucket installation dir>/lib folder

    • With a name similar to postgresql-*.*-*-jdbc*.jar (where * will be a number indicating the version of the add on)

  • Replace the located jar with the postgresql-9.4.1211.jar one

  • Start Bitbucket Server
