Deploy command fails on Deno with ERR_CRYPTO_HASH_FINALIZED #7075
Description
Describe the bug
It seems like Deno's polyfill for Node's crypto.Hash considers .end() as a finalization of the object, and so a following call to .digest('hex') fails with ERR_CRYPTO_HASH_FINALIZED.
This happens in src/utils/deploy/hasher-segments.ts function hashFile():
const hashFile = async (filePath: string, algorithm: string) => {
const hasher = createHash(algorithm)
await pipeline([createReadStream(filePath), hasher])
return hasher.digest('hex')
}pipeline() indirectly ends the hasher write stream after consuming the read stream. So the following call to hasher.digest('hex') results in an exception.
A solution that worked for me is providing { end: false } as a second parameter to pipeline(). (I also verified that this does not break running the command from node.js.)
See: Garciat/netlify-cli@main...garciat/fix-deno-digest-already-called
An alternative would be to use hasher.read().toString('hex') instead of hasher.digest('hex'), which only reads the hash result (assuming that .end() was called previously) instead of trying to finalize the hash object. However, I find this approach a bit too implicit/indirect.
Steps to reproduce
Given a project that has already been configured for deployment:
deno run -A npm:netlify-cli deployThe output was:
