Is Ukrposhta working normally for everyone? (creating TTN, etc.)

Good afternoon.
From what is known at the moment - 01.01.2025 Ukrposhta changed the API. But the changes have already been made.
If you have a specific problem - please specify.

a parcel was sent to a client, 400 grams in fact, but the Ukrainian post office claims that 400 kilograms were registered
And when switching to some status of the process "with Ukrposhta" it gives an error, where it says that something is wrong with the width

although the weight on the sticker is correct

perhaps these are different errors from Ukrposhta,
weight is one thing and what does not allow to go to the statuses of the process with ukrposhta and another error

There were no changes to the weight field from our side, only the width / height / length were transferred.
I recommend that you, together with Ukrposhta technical support, analyze the problematic request (by enabling logging of all requests in the Ukrposhta application settings) and perhaps it will become clear whether something is being transmitted incorrectly on the OneBox side and changes are needed due to the new features, or whether something is being calculated incorrectly on the Ukrposhta side.

Ukrposhta changed the pricing of shipments from January 1, now length/width/height must be filled in. If you had only weight/longest side set in the default settings, then an incorrect delivery cost was generated. Ukrposhta only installed the validator on January 4. Now there should be no more errors.
