This was a bug that was fixed I believe in 3.2:
>
>
> Mautic 3 introduced a version bump for MySQL to 5.7 (see https://github.com/maut…ic/mautic/blob/staging/UPGRADE-3.0.md#backwards-compatibility-breaking-changes), but it was never enforced in the code.
>
> This is now leading to the following error:
> \`\`\`
> 11:16:32 ERROR \[console\] Error thrown while running command "mautic:plugins:reload". Message: "Unknown database type json requested, Doctrine\\DBAL\\Platforms\\MySqlPlatform may not support it." \["exception" =\> Doctrine\\DBAL\\DBALException { …},"command" =\> "mautic:plugins:reload","message" =\> "Unknown database type json requested, Doctrine\\DBAL\\Platforms\\MySqlPlatform may not support it."\]
> \`\`\`
>
> As described in https://github.com/laravel/framework/issues/15772#issuecomment-685945057, the solution is to bump the \`server\_version\` in the Doctrine config to 5.7 as well.

> This bug is currently blocking the following things:
> \- Mautic API library to GH Actions https://github.com/mautic/api-library/pull/231 (I temporarily applied the patch in this PR to the one in \`api-library\`, and can confirm it fixes the issue https://github.com/mautic/api-library/pull/231/commits/fa9a7554ea4888fb6f5993591bc3707e58ee49c7
> \- Automatically testing a Mautic upgrade in our CI release job: https://github.com/mautic/mautic/runs/1442983812?check\_suite\_focus=true
>
> We can't reliably release 3.2 if this fix is not in.
