Alexgranata97 Posted July 4 Share Posted July 4 Hi everyone, I'm facing an issue in my PrestaShop project and I hope someone can help me resolve it. I have an AJAX call that returns some data, and I’m trying to check for the presence of a property called layout in the returned object. However, I’m getting the following error in the console log: javascript Copia Uncaught TypeError: Cannot use 'in' operator to search for 'layout' in 1 at Object.updateContent (front.js:1154:17) at Object.success (front.js:1123:8) ... The code is attempting to use the in operator on an object that appears to be a number (1) instead of an object. The error occurs in the updateContent function in the front.js file. Details: Function where the error occurs: updateContent (line 1154 in front.js) Expected data type: Object with the property layout Error type: The value passed to the function is a number (1), so the in operator cannot be used on it. I’ve already tried adding a check to verify that the data is an object, but I haven’t been able to resolve the issue. Here’s an excerpt from the code: javascript Copia if ('layout' in data) { // Perform operation with layout } What I’ve tried so far: Verifying that the data variable is an object before using the in operator. Adding type checks to ensure a non-numeric value is passed. My questions: What could be causing this problem? How can I properly handle the AJAX response to ensure non-object values are not passed? Any other suggestions for resolving this type of error? I greatly appreciate your help! Thanks in advance. Link to comment Share on other sites More sharing options...
