fastly compute deploy failing with "Failed to extract metadata from package"

[RafaelSkyMonde]

Version

Fastly CLI version v13.0.0 (a52d1a7)
Built with go version go1.24.7 linux/amd64 (2025-10-30)
Viceroy version: viceroy 0.15.0

What happened

I run the following command:

fastly compute deploy --package=../../bin/wasi/release/destiny-stage.tar.gz --dir=scripts/build --env=stage --verbose

Up until today all my projects were deploying successfully. But starting today I get:

Service version 70 is not editable, so it was automatically cloned. Now operating on version 75.

| Uploading package...
/ Uploading package...
✗ Uploading package

ERROR: the Fastly API returned 400 Bad Request: Bad request (Failed to extract metadata from package).

If you believe this error is the result of a bug, please file an issue: https://github.com/fastly/cli/issues/new?labels=bug&template=bug_report.md
../../scripts/jambase.fastly.edge(73) : Command "fastly" returned error 1

I confirmed the validity of my package:

fastly compute validate -p bin/wasi/release/destiny-stage.tar.gz
SUCCESS: Validated package /home/rafael/milk/apps/destiny/bin/wasi/release/destiny-stage.tar.gz

My build system before was building packages this way:

tar -czvf bin/wasi/release/destiny-stage.tar.gz -C bin/wasi/release/destiny-stage .

That produces packages that look like:

tar -tzf bin/wasi/release/destiny-stage.tar.gz
./
./bin/
./bin/main.wasm
./fastly.toml

But I also tried using compute pack, like this:

fastly compute pack -w bin/main.wasm

Which produces packages with a slightly different structure:

tar -tzf bin/wasi/release/destiny-stage.tar.gz
skymonde-destiny-stage/
skymonde-destiny-stage/bin/
skymonde-destiny-stage/bin/main.wasm
skymonde-destiny-stage/fastly.toml

But all packages seem to validate on the command line. But none can deploy. The embedded .toml looks like this:

# This file describes a Fastly Compute package. To learn more visit:
# https://www.fastly.com/documentation/reference/compute/fastly-toml

Apologies for this! Late last night (US time) we had to deploy some changes to our system to protect our customers using Rust on Compute (for details see our status post). It is possible that those changes have caused this problem for you, so if you would please open a support ticket using support@fastly.com our support and engineering teams will help you.

We have the same problem at my company

As noted above, please work with Fastly support. This is not a support channel, and we'll correct the CLI to stop suggesting that customers report issues here :-)

Same here! Will contact support. Thanks.

There was some kind of uploader issue at Fastly due to a recent emergency patch. The issues caused by that patch appear to be resolved, at least for me.
