Wasm file appears to be empty but not sure why as compilation is successful

[jsoneaday]

I am building a wasm project using wasm-bindgen and wasm-pack. I initialized the project with wasm-pack and I run the build inside a docker image as I need to deploy this across platforms. The build seems to succeed without issue. I can see the set of relevant bg files and the wasm file itself is 202kb.
However when I run wasm-metering on it, it fails while trying to parse the first bytes opcode as shown. When I run xxd on the file it appears to have code although the hex dump is quite large and difficult to read. How can I inspect what is happening during the file generation to figure out what's going on?
