•In our letter, we address the dominant uncertainty regarding the extent of the rp-process flow bypass around waiting point for astrophysical conditions relevant to Type-1 X-ray bursts.•We removed the final significant uncertainty, the beta-delayed proton branching ratio for , definitively determining that there is a bypass.•In addition, we also identified the second case of the exotic decay mode in the fp-shell.
