Ошибка при запуске Hyperledger Explorer

Версии:

ОС: виртуальная машина с Ubuntu 16.04

Узел: v8.11.4

PostgreSQL: 9.5.14

докер: 18.06.1-ce

докер-составить: 1.13.0

Я следую этому руководству по составлению гиперлейсов: https://hyperledger.github.io/composer/latest/tutorials/deploy-to-fabric-multi-org.html. После выполнения команды:

./byfn.sh -m up -s couchdb -a

Я присоединился к третьей организации в бизнес-сети, набрав:

eyfn.sh generate -c mychannel
eyfn.sh up -c mychannel -s couchdb

Затем я успешно построил бизнес-сеть композитора и протестировал ее на игровой площадке.

Я намеревался использовать инструмент Hyperledger Explorer для визуализации количества транзакций и их деталей.

Я выполнил шаг за шагом по этой ссылке: https://github.com/hyperledger/blockchain-explorer

При вводе в новой консоли команды для запуска Hyperledger Explorer:

./start.sh

Hyperledger Explorer не запускается и в логах консоли выдается следующая ошибка:
