Error when raising Samba 4.19 Functional Level

[feliperibeiro.ti]

Hi, I raised the functional level of my Samba 4.19 server with the commands below, the Schema update took a long time but ended successfully, however when raising the functional level with the second command the error below occurred and I was unable to complete the complete process. Can anyone tell me what could have happened or if they have experienced this?

1 - samba-tool domain schemaupgrade --schema=2019
2 - samba-tool domain functionalprep --function-level=2016
3 - samba-tool domain level raise --domain-level=2016 --forest-level=2016

Error:
