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

**Version** Fastly CLI version v13.0.0 (a52d1a7d) 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.
