General Errors
Unknown operator <operator name>
The category the Legacy Profile task is importing includes an element in angled brackets that is not one of the operators which the task can convert. For example:
Unable to parse adjacent operators
The category the Legacy Profile task is importing contains an expression in which certain operators appear immediately adjacent to each other. It is not always meaningful to place operators immediately adjacent to each other without any intervening text.
VQL could not be fully parsed—invalid use of operators—Unable to fully parse VQL
The Legacy Profile task cannot complete the VQL conversion stage of legacy profile importing for some reason other than those identified by the other error messages listed in this appendix.
