Checked the cause of the error in testing the web application, the error is when editing the pat project, the project name is set to 1, as per checking on the controller and blade there is nothing set, and when checked the field, it is returning the correct value, deployed the project controller and blade in 11.120 to check if the same error will be encountered, as per checking, it is not encountered, thus checking this on my local will not be resumed for now as this might be encountered only on my local.
Continued to check the application for checking why the two reports created are not downloading a CSV file. Modified the report for correcting the generated file name.
