My application is not bootableΒΆ

In your analysis report, you may get the violation A Symfony application should be bootable. This violations means SensioLabsInsight was not able to boot the Symfony application due to an error occuring during the boot.

A lot of things could be the reason of the failure but here are the most common ones.

Your application fails to boot because of the connection to a database not accessible.

Starting databases is usually not required, nor desirable. Even if SensioLabsInsight boots your application kernel to analyze it, theoritically, a local database should not be required.

Yet, in some cases you can see "Dependencies cannot be installed" or "SensioLabsInsight was not able to boot your Symfony application" error. The reason is that SensioLabsInsight always try to install and boot your application before analyzing it. When installing your project's dependencies, the composer install command is executed. In turn, this command executes the cache:clear command, which tries to boot the kernel of your application.

This usually indicates that Doctrine ORM is trying to guess the database server version by querying it. This can be easily resolved by using the server_version option to set this value manually:

If the issue is different, see "How to connect to a database".
