It this still an issue in 1.13 ? If so, does REALMS-1129 describe this issue?

Reading through the logs as the upload takes place leaves me with this error message:
<log4j:Message><![CDATA[[STDERR]: java.lang.RuntimeException: file name 'world/datapacks/bac_advancements/data/blazeandcave/advancements/adventure/the_great_blocky_reef.json' is too long ( > 100 bytes)]]></log4j:Message> </log4j:Event>
This leaves me to believe there is a build in restriction to file name lengths which is enforced on realms server and not on regular servers. I edited all the file names and it worked without problem.
Same data pack and error as
REALMS-1128
