Description
Environment details
- Specify the API at the beginning of the title. For example, "BigQuery: ...").
General, Core, and Other are also allowed as types - OS type and version: osX 10.15.7
- Java version: 15
- storage version(s):
com.google.cloud:libraries-bom:20.4.0
Steps to reproduce
- Start the firebase emulator suite (including storage) via the npm firebase client.
- Try to create a file using the firetstore emulator
Code example
fun createStorage(): Storage {
val storageHost = System.getenv().getOrDefault(ENV_STORAGE_EMULATOR_HOST, "http://localhost:9199")
println("Using $storageHost for the Storage host")
return StorageOptions
.getDefaultInstance()
.toBuilder()
.setHost(storageHost)
.setCredentials(NoCredentials.getInstance())
.setProjectId("test")
.build()
.service
}suspend fun Storage.upload(from: InputStream, to: BlobId): Unit = withContext(Dispatchers.IO) {
val storage = this@upload
val toInfo = BlobInfo.newBuilder(to).build()
storage
.create(toInfo)
.writer().use { writeChannel ->
val byteBuffer = ByteBuffer.allocate(2048)
from.use { from ->
Channels.newChannel(from).use { fileChannel ->
while (fileChannel.read(byteBuffer) > 0) {
writeChannel.write(byteBuffer)
}
}
}
}
}

It seems like maybe this library doesn't support the local emulator.

The emulator is part of the Firebase SDK right? It looks like you're pointing to it correctly, so it looks to me like it's a bug with the emulator, not the storage client.

See this thread. The cloud storage for firebase emulator is not compatible with any of the storage clients. It looks like you may have already done this, but please raise this to the firebase tools team as a feature request 🙏🏿 .
