'ARCore: Raw Depth Codelab is not working on my phone

I wanted to test this codelab from Google, but whenever I try to run the part3_completed file/application on my Huawei P30 ELE-L29 phone, I encounter the following errors (from logcat):

You can clone the sample code through git clone https://github.com/googlecodelabs/arcore-rawdepthapi to check it out yourself.

I'm confused because I didn't change anything in the sample code and I was expecting it to work on my phone since it supports Depth API. I've tried a different depth codelab from Google and it worked but this one somehow doesn't.

Any help would be appreciated :)

Ok I was able to fix the issue by removing the 'f' at the end of the float assignments for kMinHeightMeters and normalizedHeight. The app works now.
