error-reproduction-demo

Demo project in order to reproduce the SHA-1 error.

The issue currently affects two of our developers and completely blocks them, we are available for testing and further evaluation and would be happy to help debug this.

Our System Versions yarn expo diagnostics:

How to reproduce

We were able to reproduce the error on a fresh setup macOS System on first try. We installed brew from brew.sh and ran:

brew install git yarn nvm watchman
git clone ...
yarn install
cd applications/demo-app
yarn ios

💥💥 BOOM!!! 💥💥 Error

Synopsis

We did try to close the iOS simulator at different times of this process to no avail.
We also tried to reboot our systems before and after the yarn install as mentioned

During our research we collected the following links and evaluated/tried their suggestions:

As suggested by K999 on stackoverflow we

cleaned several temp directory paths jump to the log,
had watchman delete all its watches jump to the log and
we dropped all our node_module directories within the project jump to the log
we used the expo equivalent of npm start -- --reset-cache which is yarn start --clear. jump to the log

We also ensured metro-react-native-babel-preset is part of the babel preset config, which it is due to babel-preset-expo.

In addition we also dropped our yarn cache jump to the log.

Yairopro on stackoverflow suggested to update the global installation of react-native-cli, which in our case is not applicable as this is an expo project.

expo/expo#2743 - SHA-1 for file ..\node_modules\expo\AppEntry.js is not computed · Issue #2743 · expo/expo

As Slapbox himself suggested removing watchman from the path did not solve the issue for us and the erroneous behaviour persisted.

facebook/react-native#19478 - [master iOS]Metro Bundler has encountered an internal error, please check your terminal error output for more details · Issue #19478 · facebook/react-native

As suggested by handeglc we dropped our node_module directories throughout the project and reinstalled using yarn to no avail.

facebook/metro#175 - [master iOS]Metro Bundler has encountered an internal error, please check your terminal error output for more details

We seem to have a similar issue as described here, though there have not been any actionable suggestions for us to try.

Initial output

After initially running yarn start we got the following output. The app seems to have started twice and then crashed due to SHA-1 error.
