Hi @hx wang,

It seems that your Web App Server configuration file does not have sufficient permissions.

To resolve the issue, go to your config folder and ensure you have write permissions for the webapps.config file. The folder path depends on your operating system; replace "x"s with your MATLAB Web App Server version.

Windows:

ProgramData\MathWorks\webapps\R20XXx\config

macOS:

/Library/Application Support/MathWorks/webapps/R20XXx/config

Linux:

/local/MathWorks/webapps/R20XXx/config
