The BJetEfficiencyCorrector (https://github.com/UCATLAS/xAODAnaHelpers/blob/main/Root/BJetEfficiencyCorrector.cxx#L486) does not set a SF for jets with abs(eta)>2.5 if dec_sfBTag is available. Using the MC20 file "xAODBTaggingEfficiency/13TeV/2022-22-13TeV-MC20-CDI-2022-07-28_v1.root", the decoration is available for jets with abs(eta)>2.5, returning a SF of 1 and the message "Jet |eta| is outside of the boundary!".
This is something that could be handled at the analysis end, but since the SF is set to 1 when abs(eta)>2.5 and there is no decoration, it makes sense to do so when there is a decoration.
