In Magento, I am building a bulk image upload feature.

Here user can upload images as "sku_1.jpg, sku_2.jpg, sku_3.jpg ".

Now I need to set "sku_1.jpg" as the main image, thumbnail.

I used the following code for it. But some times it's working and some times it failed.

 try{
 $data[] = ['sku' => "sku" , 'image_name'=>"image",'status'=>"status"];
 foreach($files as $file)
 $image_count++;
 unset( $file_to_sku); 

 $file_name=$file["name"];
 $file_tmp=$file["tmp_name"];
 $generic_path = $vendorId.'/'.str_replace("-", "", date("Y-m-d"));
 if(!is_dir($path."/media/import/".$generic_path)) 
 mkdir($path."/media/import/".$generic_path,0777,true);
 
 $image_path = $path."/media/import/".$generic_path.'/'.$file_name;
 $ext=pathinfo($file_name,PATHINFO_EXTENSION);

 if(in_array($ext,$extension))
 
 move_uploaded_file($file_tmp,"pub/media/import/".$generic_path.'/'.$file_name);
 $base_filename = pathinfo($file_name, PATHINFO_FILENAME);
 $fileNameNoExtension = preg_replace("/.[^.]+$/", "", $file["name"]);
 $file_to_sku = explode("_",$base_filename); 
 $product_image_sku = $file_to_sku[0]; 
 if($product_image_sku!="")
 $prod = $this->_vproducts->getVendorProductsByVendorSkuId($vendorId,$product_image_sku);
 $vend_prod_count = count($prod->getData()); 
 if($vend_prod_count > 0)
 $product = $this->_objectManager->create('MagentoCatalogModelProduct')->load($prod->getProductId()); 
 $prod_media = $product->getMediaGalleryImages();
 $existingMediaGalleryEntries = $product->getMediaGalleryEntries();
 $product_status=$product->getStatus();
 $cmp_image=$product_image_sku."_1";
 $productRepository = $this->_objectManager->create('MagentoCatalogApiProductRepositoryInterface');
 $ext_images = array();
 if($product_status == 2)
 if($existingMediaGalleryEntries)
 foreach ($existingMediaGalleryEntries as $key => $entry) 
 $new_img=basename($entry['file']);
 $ext_images[]=$new_img;
 if($new_img==$file["name"]) 
 $this->imageProcessor->removeImage($product, $entry['file']);
 unset($existingMediaGalleryEntries[$key]); 
 
 $product->setMediaGalleryEntries($existingMediaGalleryEntries);
 $this->productRepository->save($product); 
 
 
 
 if(count($prod_media) <= 6) 
 /*Add Images To The Product*/
 if($file_to_sku[1] <= 6)
 if( $product_status == 2)
 $cmp_image=$product_image_sku."_1"; 
 if($fileNameNoExtension == $cmp_image)
 $product->setBaseImage($image_path)
 // ->setSmallImage($image_path)
 // ->setThumbnail($image_path)
 ->addImageToMediaGallery($image_path,array('image', 'small_image', 'thumbnail'),false, false);
 $product->save();

 // 
 else 
 $product->addImageToMediaGallery($image_path, null, false, false); 
 
 if($product->save())
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'success'];
 $success++;
 else
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'Image not saved'];
 
 elseif(!in_array($file["name"],$ext_images)) 

 if($fileNameNoExtension == $product_image_sku."_1")
 $product->addImageToMediaGallery($image_path, array('image', 'small_image', 'thumbnail'), false, false);
 else
 $product->addImageToMediaGallery($image_path, null, false, false);
 if($product->save())
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'success'];
 else
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'Image not saved'];
 
 
 else
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'image is not a valid extension'];
 
 else 
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'product already have 6 images'];
 
 else
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'product sku not found']; 
 
 else 
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'product sku not found'];
 
 else 
 $data[] = ['sku' => $product_image_sku , 'image_name'=>$file["name"],'status'=>'image is not a valid extension'];
 //array_push($error,"$file_name, ");
 
 

What was wrong in my code? please help me.
