"Could not exchange access token for unknown reasons" ; In-meeting App Meeting Extension

Myself and a team member have followed the 'Try this sample' and 'Use the app in Teams' instructions for the In-Meeting sample application to develop an app for Microsoft Teams:
https://github.com/OfficeDev/TeamsFx-Samples/tree/v2/in-meeting-app
We've both followed the same steps on different computers and on different OS's (Mac and PC), and we are getting the same issue:
"An error has occurred. This application may no longer respond until reloaded".
The instructions have us open Powershell and run commands in two locations. ('Try this sample' Step 5)
'tabs' folder, asked to run npm install and npm start
'bot' folder, asked to run npm install and npm run start:local
No errors occur when these commands are run initially, but when we open the app up in Teams and click on the button to bring out the side panel, errors show up in both terminals where we ran the commands.
In terminal 1, the tabs folder, we get a 'proxy error':

My team member who is on Mac, instead of getting the error I get above, just gets the message "Could not exchange access token for unknown reasons.", but his client displays the same behaviour.
These errors repeat each time we open and close the side panel.
What can we do to fix the issue, and get it to show as it's supposed to?
Steps to reproduce:
Follow steps at https://github.com/OfficeDev/TeamsFx-Samples/tree/v2/in-meeting-app
"An error has occurred. This application may no longer respond until reloaded."

Thanks for using this sample and post the issue.
For the first error occurred in tab folder, from the log
reflectrdomain.eu.rok.io to http://localhost:5000/
I found that you may not using the ngrok, so caused the proxy error, my suggestion is try ngrok first and check if it is worked.
The solution for the second issue in bot folder, is removed the app in the meeting and re-add the app into the meeting.

React Native ios run issue

I am new to react-native and running yarn ios on my react native project keeps failing with the following error.
`** BUILD FAILED **
The following build commands failed:

`

Folly hardly ever works for me.
In your Podfile, comment out the line flipper_post_install(installer) i.e:
# Use a hash to comment within Podfiles and Podspecs.
# flipper_post_install(installer)
Then reinstall pods by running either npx pod-install or by typing pod install in your Terminal from within the ios directory. You have to do this every time you modify the Podfile or install a new native binary for iOS.

expo init <project name> throwing npm ERROR (windows OS)

Just started with expo and React-Native and when I run
expo init ProjectName
I am getting an error stating:
Unexpected end of JSON input while parsing near '...,"version":"7.0.0-bet'
Process exited with non-zero code: 1
Set EXPO_DEBUG=true in your env to view the stack trace.
When I add the said thing in env (using set EXPO_DEBUG=true on windows), I get the following error:
Error: Process exited with non-zero code: 1

at maybeClose (internal/child_process.js:962:16)
at Process.ChildProcess._handle.onexit (internal/child_process.js:251:5)
It's something related to 'spawn-async'. I was also getting issues with 'spawn' sometime earlier while creating a node-server...but I resolved that there and then using 'exec' instead. Tried to find this on expo forums and even in react-native issues but couldn't find a solution. Can someone plz suggest something? Is it some "windows" thing only or something related to npm releases?
P.S: I also ran create-react-native-app ProjectName and again got a similar kind of error about end of JSON input!

Now I know what can be the issue, it can be just the trivial one:
Please update node an npm to the newest available version and please init you project again in different directory.

You'll need to have Node.js (version 10 or newer) installed on
your computer. Download the latest version of Node.js.
Additionally, you'll need Git to create new projects with Expo
CLI. You can download Git from here.
Make sure that you have installed these two things in your device.
Go to doc for expo installation

in my case. make sure you have yarn installed and update tour android studio packages, for it to work

React-Native Could not get batchedBridge Error

I am a beginner in React Native (version 0.40.0) and I have encountered a problem while developing a project. When I run npm start (npm version-4.6.0) I get no errors and the packager starts normally. Running react-native run-android also doesn't give any errors however when the app starts in the Android Emulator( Nexus 6 API 23 ) I see the "Unfortunately app had to be closed" notice. The logcats in Android Studio are:

Please let me know what I can do to resolve this issue.

I'm just going to quote a solution form this issue on the official react-native github repository.
react-native run-android
react-native start --reset-cache
To better understand how this works and to look for another solution there are several issues under similar name/tags on the issue page of the repository itself.
