Error when creating an item with fully filled fields

Hello everyone!
During use, I created an item using the create_item mutation (group id, board id, element name, column values:{"name":"value"})
since March 1, these requests have been giving an error
Code 200
The structure of the Linktoitem column value is invalid"
How to avoid this? I will have about 169 columns in the future, I can’t do mutation for each cell, please tell me what replacement to use for this query

Hi @Artur,

Welcome to the community!

Could you please share the full request being made to the API, including the mutation as it is being written?

A status of 200 indicates your request was successful. Could you also share any errors you see?
