Hi, For some of our clients we get this error message in one of our modules:

- Liquid error: next\_year only supports period end dates in code: `assign period_start_minus1 = period.minus_1y.year_start_date | date:'%Y'`
- Liquid error: next\_year only supports period end dates in code: `assign period_end_minus1 = period.minus_1y.year_end_date | date:'%Y'`

For most clients this works perfectly, anyone having an idea what can be wrong?

The code is in a shared part.

Kind regards,

Hi Anna,

This is something we also detected in our routine checks this week. You should have got a message from our Customer Sucess team with information about it. This happens for clients that have the wrong period end dates, for example:

You can check this by going into the main client’s page \> “Admin” \> “Ledgers”

Should you have any questions, please let us know.
