Hi, An unhandled exception has occurred. See browser dev tools for details. Reload(In console: Invocation canceled due to the underlying connection being closed.) , when clicked Reload it works. After doing some research i got to know that this is arising only when i add entities to Module (new Module added to solution).In Log, the error shows as [ERR] Unhandled exception in circuit '97X0b7xtEA1oi719RYRX51AXfS8y8FVO2dELunj6XLM'.

    1. Create a solution in abp suite
    2. Add a Module to solution (Create a New Module in Suite)
    3. Add the Module path to the Abp Suite
    4. Generate entity in Abp suite Crud Page Generator in the New Module
    5. Log in and you can find the reload error

    I am using Abp commercial

    Thanks
