jambonz-mini 0.8.5-2 - 504 Gateway Timeout

[mhertogs]

The jambonz-mini version 0.8.5-2 through AWS marketplace is failing to start up successfully.

Reproduction Steps Follow steps in guide: https://blog.jambonz.org/installing-jambonz-using-aws-marketplace

• Selected 0.8.5-2 as the software version.
• Launched cloudformation template with all default parameters (see screenshot below)
• Waited 30 minutes (just to ensure all setup scripts run)
• Attempted to go to http://<myElasticIP> and got a 504 Gateway Timeout

Note: I ran through the exact same procedure for version 0.8.4-3 and was successfully able to get it running.

Cloudwatch Logs

I checked the Cloudwatch logs to compare between deployments. Both the successful 0.8.5-2 and 0.8.4-3 had these error logs but since both had them, it seems likely to simply be initial timeouts that were eventually retried (i.e. red herring)

From jambonz-api-server cloudwatch logs:

    at PoolConnection._handleTimeoutError (/home/admin/apps/jambonz-api-server/node_modules/mysql2/lib/connection.js:189:17)
    at listOnTimeout (node:internal/timers:569:17)
    at process.processTimers (node:internal/timers:512:7) {
  errorno: 'ETIMEDOUT',
  code: 'ETIMEDOUT',
  syscall: 'connect',
  fatal: true

From jambonz-feature_server cloudwatch logs:
