The MAAPI throw exception when the key of a list has the space

[cohult]

@per

by definition, the keys inside the {…} of paths that you pass to the CDB/MAAPI functions are space-separated, thus you need to quote key values that have embedded spaces in order to make the intended parsing possible.

So for your “Data partition” example you need to quote it like this "\"Data partition\"". Java maapi.create() example:
maapi.create(tr, "/some/path{\"Data partition\"}");
