Hi @zmdeluyas ,
The error message you provided indicates that there is a `NullPointerException` occurring in the JSP pages related to the processing of thumbnails. This error typically occurs when there is a null value being accessed or used incorrectly in the code.
To troubleshoot and fix this issue, you can try the following steps:
1. **Check the logs**: Review the AEM logs for any additional error messages or stack traces that may provide more information about the cause of the `NullPointerException`. Look for any specific details or variables that are null or causing the issue.
2. **Review the code**: Examine the JSP pages mentioned in the error message (`form.jsp`, `newtabs.jsp`, `container.jsp`, `videoplayer.jsp`) and locate the lines mentioned in the error message (line 302 in `form.jsp`, line 183 in `newtabs.jsp`, line 84 in `container.jsp`, line 40 in `videoplayer.jsp`). Analyze the code at those lines and check for any potential null values or incorrect usage of variables.
3. **Check the configuration**: Ensure that the Dynamic Media configuration in AEM is correctly set up and that all necessary credentials and connections to the Dynamic Media Cloud Services are properly configured. Double-check the configuration files and settings to make sure there are no missing or incorrect values.
4. **Clear the AEM cache**: Clear the AEM cache to ensure that any cached data or configurations are refreshed. This can be done through the AEM Web Console or by manually deleting the cache files.
5. **Contact Adobe Support**: If the issue persists and you are unable to identify and fix the problem, it is recommended to reach out to Adobe Support for further assistance. Provide them with the error message, relevant logs, and any other details that may help them troubleshoot the issue more effectively.
Please note that without access to the specific code and configuration, it is difficult to provide a precise solution. The steps mentioned above are general troubleshooting steps that can help identify and resolve common issues related to `NullPointerExceptions` in AEM.
