~~Out of the blue, I cannot deploy to mainnet anymore. Did not update my laptop, did not update dfx, did not restarted my laptop and it was working yesterday evening. Any clue?!!??!~~ **NVM** > ❯ dfx deploy backend --network ic --no-wallet > WARN: The default identity is not stored securely. Do not use it to control a lot of cycles/ICP. Create a new identity with `dfx identity new` and use it in mainnet-facing commands with the `--identity` flag > Deploying: backend > Creating canisters… > Creating canister backend… > Error: Failed while trying to deploy canisters. > Caused by: Failed while trying to deploy canisters. > Failed while trying to register all canisters. > Failed to create canister ‘backend’. > In order to create a canister on this network, you must use a wallet in order to allocate cycles to the new canister. To do this, remove the --no-wallet argument and try again. It is also possible to create a canister on this network using `dfx ledger create-canister`, but doing so will not associate the created canister with any of the canisters in your project. ---

I need a second coffee 😅, the `canister_ids.json` was not there.
