HTTP 500 Internal Server Error - Azure Bot Serivice

I have developed a bot on node.js as a teams app using the yo teams generator. The bot is hosted and deployed on an azure app service web app. The bot was working fine all the while, but started throwing http 500 internal server errors in the past couple of weeks.
I am not sure what has changed, but I am trying to fix this issue but not finding any leads and useful information from appInsights or the trace logs. All I see is the below exception being thrown in appInsights:
"POST to the bot's endpoint failed with HTTP status 500"
The bot works perfectly fine locally, when debugging through ngrok. Please let me know how I can fix this or where I can look for useful logs to help resolve this.
I was able to resolve this with MS on a support ticket. Looks like the fix is to update the configuration setting to reflect the latest version of node from 12.13 to 16.13.0 in the app service config section.

SonarQube bulk update gives error 502

We have several customer projects hosted on our sonarqube instance and couple of project teams reported issues while using bulk update feature. When tried to update 10+ issues for 2+ fields they get a 502 issue. I tried this on our dev instance and faced the same issue. IIS\Sonar\Web logs do not show any error.
Has someone seen this error? Can someone let me know what could be going wrong.
FYI, we do not have a proxy server hop for our dev instance so when a request is made the request is directly sent to the server hosting sonarqube instance whereas the production instance has a proxy server configured.
SonarQube Version : 6.1
Please let me know if any further clarification would be needed on the question.

Are you trying to send the mails from your local machine, or is the site already hosted on the live server ? If its local, mails wont go.
If you are on live server, you would have unconfigured mail service. As magento, by default would send mails if your mail server is configured perfectly.

The Local SharePoint Server Is Not Available With A Twist

I am trying to deploy a web part on to our local Sharepoint Server. I am doing this through a remote login to the same server that our SharePoint site collection is on. However, I am getting "Error occurred in deployment step 'Recycle IIS Application Pool': Check that the local SharePoint server is not available." This is universal on any code I try to deploy to the Server.
Normally it would just be an issue of making me a DB_Owner on the content database. However, the other developers are not db_owners and they can deploy just fine.
I checked the log and found a entries that might be a clue to what is going on.
System.Data.SqlClient.SqlException: Login failed for user 'domain\username'
CanUpgrade [SPConfigurationDatabase] failed.
IsBackwardsCompatible [SPConfigurationDatabase] failed.
I apologize for not posting the entire log, but company policy will not let me post the entire log.
So, does anyone know the cause of the error and how to fix it?
