Hi @sahilkapoor89 , thanks for writing in.

Looks like this might be an issue with the SAM CLI; I'd recommend taking a look at the issue here: aws/aws-sam-cli#1336

In the meantime, can you try running your code out of the C:\ drive?

[sahilkapoor89]

@bryceitoc9 As per your suggestion I moved my code to the C:\ drive but still the build was failing with the same error. Finally I figured out that my VSCode was installed on the D:\ drive and once I moved VSCode to C:\ drive everything started working.
