YAML document exceeds the limit

Hi,

using API api/ee/serialization/export I have exported a collection, but importing the collection with api/ee/serialization/import results in a error:

ERROR serialization.api :: Error during serialization
org.yaml.snakeyaml.error.YAMLException: The incoming YAML document exceeds the limit: 3145728 code points.

Has anyone had this problem and how to solve it?
Thanks in advance.
kr, Janez
