You can use json decode Your variable Name    json decode  result    I was getting value from Model where a column has value like this way    dayList                  day   1 2 3 4   time     in time   10 00     late time   15 00     out time   16 15                                   day   5 6 7   time     in time   10 00     late time   15 00     out time   16 15                      so access this value form model  you have to use this code    dayTimeListObject   json decode  settingAttendance- gt bio attendance day time 1     foreach    dayTimeListObject  dayList   as  dayListArr          foreach    dayListArr  day   as  dayIndex                  if   dayIndex    Date  w  strtotime  2020-02-11                              dayTimeList   dayListArr  time                           return  dayTimeList 2   out time       You can also define caste in your Model file    protected  casts          your-column-name    gt   json         so after this no need of this line      dayTimeListObject   json decode  settingAttendance- gt bio attendance day time 1     you can directly access this code    settingAttendance- gt bio attendance day time

I got this issue when I used an ajax call to retrieve data from the database  When the controller returned the array it converted it to a boolean  The problem was that I had  invalid characters  like     u with accent

Your response must return some sort of Response object  You can t just return an object   So change it to something like   return Response  json  promotion     or my favorite using the helper function   return response  - gt json  promotion     If returning a response doesn t work it may be some sort of encoding issue  See this article  The Response content must be a string or object implementing   toString      quot boolean  quot  given  quot

So  rather return the whole object first  just wrap it to json encode and then return it  This will return a proper and valid object   public function id  id        promotion   Promotion  find  id       return json encode  promotion       Or  For DB this will be just like   public function id  id        promotion   DB  table  promotions  - gt first        return json encode  promotion       I think it may help someone else

TL DR  Just returning response  - gt json  promotion  won t solve the issue in this question   promotion is an Eloquent object  which Laravel will automatically json encode for the response  The json encoding is failing because of the img property  which is a PHP stream resource  and cannot be encoded   Details  Whatever you return from your controller  Laravel is going to attempt to convert to a string  When you return an object  the object s   toString   magic method will be invoked to make the conversion   Therefore  when you just return  promotion from your controller action  Laravel is going to call   toString   on it to convert it to a string to display   On the Model    toString   calls toJson    which returns the result of json encode  Therefore  json encode is returning false  meaning it is running into an error   Your dd shows that your img attribute is a stream resource  json encode cannot encode a resource  so this is probably causing the failure  You should add your img attribute to the  hidden property to remove it from the json encode   class Promotion extends Model       protected  hidden     img            rest of class

It is being pointed out not directly in the file which is caused the error  But it is actually triggered in a controller file  It happens when a return value from a method defined inside in a controller file is set on a boolean value  It must not be set on a boolean type but on the other hand  it must be set or given a value of a string type  It can be shown as follows    public function saveFormSummary Request  request                      status   true        return  status         Given the return value of a boolean type above in a method  to be able   to solve the problem to handle the error specified  Just change the   type of the return value into a string type   as follows    public function saveFormSummary Request  request                      status    true         return  status
