TypeError: Cannot read property 'length' of undefined (leven)

[e-e]

This happened after downgrading to adonis/core version ~5.0.4-preview-rc-2.1 due to the BodyParser IoC error.

[e-e]

Also happens when running node ace without any commands, which used to generate the same output as node ace --help

@thetutlage @RomainLanz sorry for the direct ping, but any ideas? is there something wrong with my package.json versions? is there an update to when the v5 stable, non-preview version will be released?

[thetutlage]

Already mentioned in Discussions that one should not blindly update all the dependencies unless there is a documented release. Please do not create new issues and check existing discussions. It creates unnecessary work for us

[e-e]

I did not "blindly" update packages. I changed my node version, which introduced the error as explained in this discussion. Notice how I posted a question that went unanswered. I also posted multiple times in Discord, also unanswered.

I had the same problem and I fixed it with this:

• Delete ace-manifest.json from the root folder
• Now, node ace will work but you will have some commands missing. If you execute, node ace make:command Test the ace manifest will be recreated.
• Now you can execute node ace and you will have all your commands available.
