Java application hosted on Azure App Service giving 200 Web App Error

Aayush Suresh Jain 151

I have a Java application hosted on Azure App Service, with three different App Services for DEV, Test, and Production environments. Even though all three have the same code deployed, the Production instance has started giving an error where image HTML content is being added to Javascript files that causes strange behavior and prevents some parts of the application from loading correctly. How can I fix this, considering that there are no logged errors on Application Insights, no changes have been made to the application, and this is a problem unique to the Production instance?

@Aayush Suresh Jain Hello! Based on the information you provided, it seems like there might be an issue with the deployment process or configuration of the Production instance. Here are some steps you can take to troubleshoot the issue:

Check the deployment logs for the Production instance to see if there were any errors during the deployment process. You can access the deployment logs by going to the Azure portal, selecting the Production instance, and then selecting "Deployment Center" from the left-hand menu. From there, you can view the deployment logs to see if there were any errors during the deployment process.

Check the configuration settings for the Production instance to ensure that they match the configuration settings for the DEV and Test instances. Specifically, check the Application Settings for the Production instance to ensure that they match the Application Settings for the DEV and Test instances. You can access the Application Settings by going to the Azure portal, selecting the Production instance, and then selecting "Configuration" from the left-hand menu.

Check the version of the Application Insights agent that is being used by the Production instance. Ensure that it is the same version as the DEV and Test instances. You can check the version of the Application Insights agent by going to the Azure portal, selecting the Production instance, and then selecting "Application Insights" from the left-hand menu.

@SnehaAgrawal-MSFT Hello Sneha,

I had already done all of the troubleshooting mentioned as above.

I found the cause of the issue and it has been resolved now.

The configurations are same for the three environments but I tried changing the Tomcat version from auto select to specific version 9.0.54 and that did the trick.
