Significance

The software requires a readable, writeable application.yml configuration file co-located with its JAR file and supporting scripts in order to work.

This error indicates one or more of the following states:

  • This configuration file has been corrupted.

  • This configuration file is not readable or writable, per file permissions.

Resolution

Attempt the following tasks in the order shown:

  1. If this file exists as a text file in the expected place but is not readable or writable, correct file permissions (and) re-run the software normally, once complete.

  2. Otherwise, follow the Resetting Configuration maintenance steps for resolution.
