The SC-70 package with ”SVAJE” (pics on Convoy’s store) on it is an Op-Amp, no idea which one exactly but that resistor is connected to its output and then to the FB pin of the boost regulator on the other side (TPS61088), 120k sounds like a plausible value, the exact value isn’t critical but if shorted or unconnected the driver wont work properly.
See the shematic of this driver it’s a different driver but the principle is the same, the resistor is R9.
Edit : wait no that doesn’t correspond to an sc-70 package op-amp, rather an SOT-23 one.
