I am trying to run a react native project on the simulator using expo go. However, I am getting errors.
What I tried:
package.json has the version 34.0.0 for expo.
When running this on the simulator I get the below issue.
I then try to upgrade my expo, but getting an error there too.

I am getting the below error in my GCP Cloud Run service:
Error: Could not find or load main class com.sdas.demo.sd.Application
Caused by: java.lang.ClassNotFoundException: com.sdas.demo.sd.Application
What I was doing:
I have a spring boot application where I used jib-maven-plugin. In BitBucket pipeline, I was executing the below command:
mvn clean compile com.google.cloud.tools:jib-maven-plugin:3.1.4:build -Dimage=eu.gcr.io/sdas-demo-dev/temp-service
After that deploying this GCR image to Cloud Run using gcloud command from BitBucket pipeline. This deployment failed with the error that 'Could not load main class'.
But if I run the mvn clean compile com.google.cloud.tools:jib-maven-plugin:3.1.4:build -Dimage=eu.gcr.io/sdas-demo-dev/temp-service from my computer git bash for the same spring boot application code and then deploy it to Cloud Run (via gcloud command or via console or via pipeline); it's deployed successfully.
I used 'mainClass' tag under jib-maven-plugin in pom.xml. But still it is unable to find or load the main class.
Can anyone help how to identify the problem? Is this a classpath issue or environment issue?
Issue sorted now.
Root cause:
'No resources found to compile' - I found this message in the build log. This message remind me something wrong within the application package.
My system is running on Windows 10 and my application directory starting with 'Java.com.demo.sdas' (J in capital). Since Windows is case in sensitive; it is not causing an issue.
BitBucket pipeline running on Linux server and it is case sensitive. Thus it is unable to find the application directory starting with 'Java.com.demo.sdas'.
Solution: Renamed the directory as 'java' and then everything is working as expected.
I tried to run expo start or yarn start and the console threw an error. On wsl1 it is working fine, it shows the QR code. However, I have to switch to wsl2 to set up mysql for my local server and now expo is not starting.
Also sometimes the QR code shows up but when I try to open the app in my device, the same error shows up.

I think the problem here is expo itself. I tried to I check the developer tools url, the site cant be reached. I also tried to check my account using expo login and this error shows up

jest-haste-map: Watchman crawl failed. Retrying once with node crawler. Usually this happens when watchman isn't running. Create an empty .watchmanconfig file in your project's root folder or initialize a git or hg repository in your project. Error: Watchman error: query failed: synchronization failed: Connection timed out. Make sure watchman is running for this project. See https://facebook.github.io/watchman/docs/troubleshooting.html.
I tried multiple fixes but no luck.
1. set `REACT_NATIVE_PACKAGER_HOSTNAME` to my ip using `export`
2. delete `.expo` from root of project and run `expo start -c`
3. turn off windows defender and firewall
4. update `expo-cli` to latest (4.4.1)
5. restart laptop
Maybe this GitHub issue describes your problem and the workaround?
This can usually happen when publishing without ever having run expo start, also it's a good idea to run rm -rf .expo to clear your local state
it's listed in our common development errors
Your latest edit shows this error message and suggested fix: Usually this happens when watchman isn't running. Create an empty .watchmanconfig file in your project's root folder or initialize a git or hg repository in your project. Did you try that?
I am having issue deploying a react project to heroku, I checked my heroku logs and i see that heroku is having problem running npm build.
After googling around i found out that i need to degrade my react-scripts from 3.1.2 to 3.0.1 and heroku build it successfully.
But Heroku is still displaying
Application error
so I had to run build myself locally, I am getting a blank page and I see on my chrome console this error:
TypeError: t.map is not a function - react-dom.production.min.js:4483
Note: yarn start is running the application locally without any error.
