Troubleshooting

Sometimes things go wrong and Part-DB shows an error message. This page should help you to solve the problem.

Error messages

When a common, easily fixable error occurs (like a non-up-to-date database), Part-DB will show you some short instructions on how to fix the problem. If you have a problem that is not listed here, please open an issue on GitHub.

General procedure

If you encounter an error, try the following steps:

  • Clear the cache of Part-DB with the console command:
php bin/console cache:clear
  • Check if the database needs an update (and perform it when needed) with the console command:
php bin/console doctrine:migrations:migrate

If this does not help, please open an issue on GitHub.

Search for a user and reset the password

You can list all users with the following command: php bin/console partdb:users:list To reset the password of a user you can use the following command: php bin/console partdb:users:set-password [username]

Error logs

Detailed error logs can be found in the var/log directory. When Part-DB is installed directly, the errors are written to the var/log/prod.log file.

When Part-DB is installed with Docker, the errors are written directly to the console output. You can see the logs with the following command, when you are in the folder with the docker-compose.yml file

docker-compose logs -f

Please include the error logs in your issue on GitHub, if you open an issue.

KiCad Integration Issues

"API responded with error code: 0: Unknown"

If you get this error when trying to connect KiCad to Part-DB, it is most likely caused by KiCad not trusting your SSL/TLS certificate.

Cause: KiCad does not trust self-signed SSL/TLS certificates.

Solutions:

  • Use HTTP instead of HTTPS for the root_url in your KiCad library configuration (only recommended for local networks)
  • Use a certificate from a trusted Certificate Authority (CA) like Let's Encrypt
  • Add your self-signed certificate to the system's trusted certificate store on the computer running KiCad (the exact steps depend on your operating system)

For more information about KiCad integration, see the EDA / KiCad integration documentation.
