In Japanese, 一度 (いちど (ichido)) is typically associated with "once; one time; a single time; at one time; for a time; once (upon a time)" (Syllabus Level: N3) and represents Indicates a single occurrence or instance. Can also mean 'once upon a time' or 'for a while'. Often used with verbs like 'try'.
On the other hand, 一応 (いちおう (ichiō)) maps to "once; for now; in any case; tentatively; for the time being" (Syllabus Level: N2) and represents Implies that something is done provisionally, temporarily, or to a certain extent, but might not be perfect or final. Can also mean "just in case" or "for now.". A literal translation of "once" can often sound unnatural to native Japanese speakers if mixed up!
