E0035

The account handle has an invalid format.

Use only ASCII letters, digits, and hyphens. Leading and trailing whitespace is trimmed and uppercase ASCII letters are saved in lowercase. A handle cannot start or end with a hyphen or consist of exactly 32 hexadecimal characters. Self-service claims also enforce the length bounds reported in the error message; admin assignments bypass those bounds.

Choose a handle in that format and retry. Reserved handles are refused separately with E0036.
