[2.0.28] Error when setting storage_filter to nil on storage chests
Posted: Sun Jan 12, 2025 12:55 pm
What did you do?
I attempted to clear the storage_filter of a storage chest in my mod by setting the storage_filter property to nil. This was done using the following code:
To reproduce:
1. Hover over a storage chest in-game.
2. Press the shortcut key defined in the mod to trigger the script above.
What happened?
When executing the code, the game produced the following error:
This error occurred regardless of whether the chest currently had a filter set or not.
What did you expect to happen instead?
I expected the storage_filter property to accept nil and clear the filter on the storage chest without causing an error. This expectation aligns with the documentation for the storage_filter property, which indicates it is nullable.
Does it happen always, once, or sometimes?
This issue occurs consistently every time the code is executed.
Additional Context
The storage_filter documentation (https://lua-api.factorio.com/latest/cla ... age_filter) indicates that this property is nullable, and reading the storage_filter property of a chest without a filter correctly returns nil.
