@yuichiroaoki any chance you could look into this bug? thanks!

I get the same error. I also edited the loan amount. I'm not sure if that's related but it is something we both have in common.

[adedade]

I did get that error also with the default loan amount unfortunately

[yuichiroaoki]

My bad. The problem was because of the poor error handling of axios response. Will fix that.

[adedade]

I saw that you pushed some updates. I've pulled the latest changes and will check if the issue is resolved :)

[adedade]

Great job @yuichiroaoki, it works well!
