It should be
for i, negSampleWordIdx in enumerate(negSampleWordIndices):
gradOutsideVecs[negSampleWordIdx] += (1.0 - z[i]) * centerWordVecfrom cs224n-2019-solutions.

Use np.add.at() to avoid for loop, lets keep integrity of vectorization ^^. kudos.
Replace line 147 with:
np.add.at(gradOutsideVecs, negSampleWordIndices, np.outer((z-1),centerWordVec)*(-1))
