botbuilder-js: Error: BotFrameworkAdapter.processActivity(): 401 ERROR

Versions

botbuilder: 4.9.2 (Latest) node: 12.18.2 (Latest) OS: Ubuntu (Docker-Container)

Describe the bug

One of a sudden adapter.processActivity fails with these two error messages when sending a chat-message to the bot:

1. Error Message: JwtTokenExtractor.getIdentity:err!

Details

I created my bot via the App-Studio. I don’t have an azure subscription. I neither use the emulator. The bot runs locally. I am using ngrok to tunnel the requests to my PC.

What I have tried

• I tried various versions of your (awesome) package
• I checked the client-id & the client-secret
• I created a new client-secret
• I verified my client-id & my client-secret
• I checked my messaging endpoint
• I verified the system time
• I created a new bot via the App Studio and the https://dev.botframework.com
• Installing xmlhttprequest manually

Code:

` … const bot = new Bot(); export const adapter = new BotFrameworkAdapter({ appId: msteams.CLIENT_ID, appPassword: msteams.CLIENT_SECRET }); MicrosoftAppCredentials.trustServiceUrl( “https://smba.trafficmanager.net/emea/” ); … expressApp.post(“/bot”, secure((req, res) => { adapter.processActivity(req, res, async context => { // <-- error await bot.run(context); }); }));

`

I am desperate, because we need to deliver a new version of our bot. But, I just can’t fix this issue. I really appreciate any help.
