fix: crash after try to patch ios (Crash occurred when compiling unknown function in AOT mode in unknown pass)

[rizkijuliansyaham]

Description

I have no issues with the iOS release, but when applying a patch for iOS, I encounter errors. However, debugging on the simulator runs smoothly without any problems

Steps To Reproduce

When I apply a patch, an error like this appears

Building patch with Flutter 3.24.3 (5a6dc546e8)... (711.2s)Exited with code -6

For starters, can you share your app id, the release version, and the patch number where you saw this?

[felangel]

Can you share the release version as well as the full patch command that you ran? Thanks!

[rizkijuliansyaham]

Can you share the release version as well as the full patch command that you ran? Thanks!

this is my full patch cmd :

shorebird patch ios -t lib/main.dart --flavor prod --dart-define-from-file=env_prod.json --verbose

and the release version is 3.2.14+71

Thanks

[bryanoltman]

@rizkijuliansyaham Out of curiosity, does this happen every time? If you create a new app using flutter create my_new_app, create a release, and attempt to patch it, do you see the same error?

[Richard-Van-Intania]

3.24.3 same error message here when build ipa, run on simulator no problem

[bryanoltman]

It's unsurprising that this would run on the simulator, as that isn't using shorebird at all.

Does this command show you a path to a log file when it exits? If so, can you share it here?

command: shorebird patch ios --flavor prod

[bryanoltman]

Thank you! Forgot to ask earlier: what is your app id?

[Oladips]

This is the app id: 802410a9-2b63-486b-bb6a-d314c94075fb

[bryanoltman]

Hmm, it appears as though we don't have an app with that ID. Was it deleted, perhaps?

[Oladips]

No it wasn't, it has a flavor config This is the prod id: 70f58f3e-115c-4732-9027-354319eb0a44

[bryanoltman]

Thank you! I'm not seeing anything obviously wrong—you seem to be running on the latest macOS and using a recent enough Xcode. Can you run shorebird cache clean and then try the patch command again?

[Oladips]

I cleared my shorebird cache. Any shorebird command I run returns this.

my-app git:(v3) ✗ shorebird Updating Flutter... error: The following untracked working tree files would be overwritten by checkout: .ci.yaml .gitattributes .github/ISSUE_TEMPLATE/10_feature.yml .github/ISSUE_TEMPLATE/1_activation.yml .github/ISSUE_TEMPLATE/2_bug.yml .github/ISSUE_TEMPLATE/3_feature_request.yml .github/ISSUE_TEMPLATE/4_performance_others.yml .github/ISSUE_TEMPLATE/5_performance_speed.yml .github/ISSUE_TEMPLATE/6_infrastructure.yml .github/ISSUE_TEMPLATE/7_cherry_pick.yml .github/ISSUE_TEMPLATE/8_design_doc.yml .github/ISSUE_TEMPLATE/9_first_party_packages.yml .github/ISSUE_TEMPLATE/config.yml .github/PR_TEMPLATE/PULL_REQUEST_CP_TEMPLATE.md .github/PULL_REQUEST_TEMPLATE.md

[Oladips]

Then it goes long and at the end I see Aborting

[bryanoltman]

Very odd, it looks like something got corrupted with your shorebird installation. If you try reinstalling shorebird (usually this is rm -rf ~/.shorebird and then curl --proto '=https' --tlsv1.2 https://raw.githubusercontent.com/shorebirdtech/install/main/install.sh -sSf | bash), does the problem go away?

[Oladips]

This fixes it but I still get the same error

That looks like the artifacts are outdated. This error means that gen_snapshot is expecting a newer kernel format and we are using the older kernel format. Does the error also occur if you create a brand new flutter app (flutter create example -e) and release/patch with a fresh shorebird installation?

Can you also share the md5 of your gen_snapshot executable?

md5 ~/.shorebird/bin/cache/flutter/5a6dc546e8ecd01fe3b9527f082ff2d6864374f9/bin/cache/artifacts/engine/ios-release/gen_snapshot_arm64

[Oladips]

This is the md5:

MD5 (/Users/----/.shorebird/bin/cache/flutter/5a6dc546e8ecd01fe3b9527f082ff2d6864374f9/bin/cache/artifacts/engine/ios-release/gen_snapshot_arm64) = b0e1d4c654e8ec7fefcae519fc54c0b9

Do you mean I should create a new app and try it with shorebird release/patch, I need clarification on this?

At the moment, release works fine, no issues. Patch works fine on android, only iOS has this issue

[felangel]

Do you mean I should create a new app and try it with shorebird release/patch, I need clarification on this?

Yeah I meant is this only happening in your current project or does it happen in a new empty Flutter project as well?

[Oladips]

This happens only in my current project, it's theonly one I have running on shorebird

[felangel]

Sounds like we're using the wrong app.dill. Can you try removing your build directory and trying again?

[Oladips]

It's just running infinitely

[felangel]

It's just running infinitely

Can you re-run with the -v flag to see what step is taking so long?

[Oladips]

[felangel]

Can you share the contents of build/link.jsonl?

[Oladips]

I can't find the aforementioned file in my build folder.

[felangel]

Hmm are you able to make a minimal reproduction sample? If not I'm happy to jump on a call to debug. The easiest way is to ping us on Discord.

[Oladips]

Hi, sorry for the late reply, I am not able to make a reproduction sample.

[rizkijuliansyaham]

@rizkijuliansyaham Out of curiosity, does this happen every time? If you create a new app using flutter create my_new_app, create a release, and attempt to patch it, do you see the same error?

I am sorry for late respond. at new project my condition is same with @Oladips , new project running normally.
