Morphology

in + the + line + of + duty

The phrase is largely compositional — 'in' (within) + 'line' (here with a metaphorical sense of area or scope) + 'duty' (responsibility) points to something occurring while performing one's responsibilities, so a learner can grasp the general sense. However, the use of 'line' in 'line of duty' is a conventionalized, non-literal metaphor (scope/role) and carries an official/legal nuance that may not be fully predictable to a B1 learner without prior exposure.

Etymology

The phrase in the line of duty comes from the image of soldiers or officers standing in a line doing their work, so being in the line meant you were carrying out your duty and could face danger. That's why it means 'while performing one's job'.
