\href in bibtex not working

I use href in my bibtex file; for example, 

@unpublished{GTV,
title = {Graph-based regularization for regression problems with alignment and highly-correlated designs},
author = {Y. Li and B. Mark and G. Raskutti and R. Willett and H. Song and D. Neiman},
note = {accepted to SIAM Journal on Mathematics of Data Science, \href{https://arxiv.org/abs/1803.07658}{arXiv:1803.07658}},
year = 2020
}

But the web page generated at https://bibbase.org/show?bib=https%3A%2F%2Fvoices.uchicago.edu%2Fwillett%2Ffiles%2F2020%2F03%2FWillettMerged.bib&msg=embed doesn't display the link properly; rather, it shows

Graph-based regularization for regression problems with alignment and highly-correlated designs. Li, Y.; Mark, B.; Raskutti, G.; Willett, R.; Song, H.; and Neiman, D. 2020. accepted to SIAM Journal on Mathematics of Data Science, \hrefhttps://arxiv.org/abs/1803.07658arXiv:1803.07658

How should I fix this? Should I use something besides href for links to papers?

Thanks for the help!
