When rendering the view page, an error error on line ... at column ...: xmlParseCharRef: invalid xmlChar value ... occurs. This error happens because the form contains a character not interpreted by the XML parser, causing the page to fail during rendering.

This field was checked in the checkbox on the form List Fields.

Simulation

1. Access the view page in the system.

2. Load a form containing a field with a character not supported by the XML parser.

3. On Chrome dev tools observe that the page fails to render and displays the following

   error: error on line ... at column ...: xmlParseCharRef: invalid xmlChar value ...

Workaround

Identify the field containing the unsupported character. Remove the invalid character from the field's value using API. Reload the page to verify that it renders correctly.
