It was discussed on the tooling call that it was possible to deploy a zipped wasm and the replica would take care of decompressing it. I was trying to do this with dfx 10 by zipping my wasm and creating a different dfx project that referenced the compressed file. When I try to install I get
Error: The Replica returned an error: code 5, message: “Wasm module of canister a4lpi-tiaaa-aaaaa-aadka-cai is not valid: Wasmtime failed to validate wasm module wasmtime::Module::validate() failed with Bad magic number (at offset 0)”
Is it possible to do this with the local replica? Or is it just a mainnet feature?
Hi @skilesare !
What program do you use to compress the module? The replica currently supports only GZip-compressed modules:
You can use either gzip or pigz to compress the module.

Ok. I was right clicking compress on Mac and I’m guessing that won’t work. I’ll try gzip which will work better from the command line anyway.
This still isn’t working for me. I get
Error: The Replica returned an error: code 5, message: “Wasm module of canister rrkah-fqaaa-aaaaa-aaaaq-cai is not valid: Wasmtime failed to validate wasm module wasmtime::Module::validate() failed with Bad magic number (at offset 0)”
config is:
“ledger”: {
“wasm”: “./ledger-canister.wasmr-min20220527ledgerfix.wasm”,
“type”: “custom”,
“candid”: “…/…/modules/ogy_ledger_canister/ledger_dfx_v2.did”
},
This file was gzipped and I took the .gz off the end(because it didnt’ work with that.
