[bug] Can't Set L in Cron. had an invalid cron pattern: Element 'L of daysOfMonth field is invalid. (Input cron: '30 18 L * *')

[DynamiteC]

Getting Above Error While Setting up Cron Job for Last Day of month at 6:30pm time. As per the guidelines the cron is supported.

    // runs `./jobs/worker-11.js` at midnight on the last day of month
    {
      name: 'worker-11',
      cron: '0 0 L * *'
    },

I got referenced from above, how to resolve this.

This is my code.

const bree = new Bree({
  logger,
  jobs: [{
    name: 'testJob',
    cron: '30 18 L * *'
  }]
});

This is the full error.

Error: Job #1 named "testJob" had an invalid cron pattern: Element 'L of daysOfMonth field is invalid. (Input cron: '30 18 L * *')

add

      cronValidate: {
        override: {
          useLastDayOfWeek: true
        }
      }

to your job configuration. Will be adding this to the docs thanks for catching it.

@shadowgate15 @niftylettuce Hi, This still didnt workout.

I tried both ways

    cron: '30 18 L * *',
    cronValidate: {
      useLastDayOfMonth: true
    }

as well as

    cron: '30 18 L * *',
    cronValidate: {
      override: {
        useLastDayOfMonth: true
      }
    }

It shows same error.

Error: Job #1 named "testJob" had an invalid cron pattern: Element 'L of daysOfMonth field is invalid. (Input cron: '30 18 L * *')

Just to confirm, which version of Bree are you using?

I have found a workaround this.

hasSeconds: true,
cronValidate: {
   override: {
        useLastDayOfMonth: true
      }
    }
