No error when calling a post api in .net 7.20

Describe the bug

        public async Task<IActionResult>  TemplateDetail([FromBody] Dictionary<string, object> rowData)
        {
        if (rowData == null)
        {
            return BadRequest("No data received");
        }
        TempData["RowData"] = rowdata';
      
        return Ok(new {data = rowData});
        } 

When i call this controller from an ajax, everything seems to be working but, when I receive the response on the front ent it says error 500.

The error also does not appear when i wrap the function in a try catch. I'm not sure if this is a bug for the C# dev kit or here.
