## Description

### Before filing a report

*Before you file a report, please ensure you are running the latest version of OpenProject and*   
*have searched for similar bug reports.*

### Steps to reproduce

*Please write down the steps to reproduce. Try to write down all necessary preconditions (what permissions do you have, are other users involved?). Example:*

1.  Have an "old Style" (pre-13.4.x) string / URL for a specific filtered project list  
    Example: "/projects?filters=%5B%7B%22active%22%3A%7B%22operator%22%3A%22%3D%22%2C%22values%22%3A%5B%22t%22%5D%7D%7D%2C%7B%22cf\_32%22%3A%7B%22operator%22%3A%22%3D%22%2C%22values%22%3A%5B%2263%22%5D%7D%7D%2C%7B%22cf\_34%22%3A%7B%22operator%22%3A%22%3D%22%2C%22values%22%3A%5B%222006%22%5D%7D%7D%5D"

2.  Try to use this URL with OpenProject 13.4.1

### What is the buggy behavior?

*Please describe the bug in as much detail as possible. Example:*

  - The project list cannot be displayed, the following error is displayed:
    
    <img class="image_resized op-uc-image op-uc-image_inline" style="width:573px;" src="/api/v3/attachments/99421/content">

### What is the expected behavior?

*Describe how the application should behave like. Example:*

1.  In the past, we have encouraged our users to save their filter strings / URLs to specific filtered project lists so that they can be accessed quickly when needed, as the option to save them was previously not supported by OpenProject. Individual departments have placed numerous links to filtered project lists in an organizational structure and now are no longer able to use them.  
    Is there a way to make the existing filters usable again ( perhaps with minor adjustments) or do all these filters have to be recreated in order to comply with the string scheme required after the update?

2.  Backward compatibility of the project filter strings would be helpful
