What's Your Problem

I am experiencing an issue while trying to configure the ecoharmonogram integration for the location:

Town: Bestwina
District: Bestwina

When attempting to set up the integration for this specific address, I encounter the following error message:

The source returned an invalid response: "day is out of range for month". Please check the provided arguments and try again.
This error prevents successful configuration and data retrieval for the specified location.

It appears there might be an issue with how the system is processing date information for this particular region or address within the ecoharmonogram data source.
