Magento 2 Solved: cluster_block_exception

error: cluster_block_exception [TOO_MANY_REQUESTS/12/disk usage exceeded flood-stage watermark, index has read-only-allow-delete block] .

This error means you do not have enough disk space to store or update data. The flood storage watermark is 95% default, so when it exceeds, the above error is shown and it puts the Elasticsearch into read-only mode. So you need to free up disk space or enlarge it.

Steps to Solve Reindex issue with Elasticsearch: run below cmd

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

Magento 2 Add Attribute Name To Configurable Select Option 'Choose a option..'

Configurable products display 'Choose an option...'. with Attribute option label like 'Color Choose an option...'


You also need to change that text in below file,

vendor/magento/module-configurable-product/view/frontend/web/js/configurable.js
In this file, you need to find _fillSelect method and see "chooseText" value.

element.options[0].innerHTML = this.options.spConfig.chooseText

Replace with below code


var attribute_lable = this.options.spConfig.attributes[element.id.replace(/[a-z]*/, '')]['label']; element.options[0].innerHTML = attribute_lable +' ' + this.options.spConfig.chooseText;

Line no 57
Replace this function

            if (!empty($tags)) {
                $this->getCache()->clean(\Zend_Cache::CLEANING_MODE_MATCHING_ANY_TAG, array_unique($tags));
            }
        }

use Magento\Framework\App\Bootstrap;
require __DIR__ . '/app/bootstrap.php';
$params = $_SERVER;
$params[Bootstrap::PARAM_REQUIRE_MAINTENANCE] = true; // default false
$params[Bootstrap::PARAM_REQUIRE_IS_INSTALLED] = false; // default true

$bootstrap = Bootstrap::create(BP, $params);

$obj = $bootstrap->getObjectManager();
$state = $obj->get('Magento\Framework\App\State');
$state->setAreaCode('global');

$quote = $obj->get('\Magento\Checkout\Model\Cart');

$product_id=66;
$_product = $obj->create('Magento\Catalog\Model\Product')->load($product_id);
 $selectionCollection = $_product->getTypeInstance(true)
                           ->getSelectionsCollection(
    $_product->getTypeInstance(true)->getOptionsIds($_product),$_product);
    // create bundle option
    $cont = 0;
    $selectionArray = [];

    foreach ($selectionCollection as $proselection){ 
       
                $selectionArray[$cont] = $proselection->getSelectionId();
                $selectionqtyArray[$cont] = $proselection->getSelectionQty();
                $selectionpriceArray[$cont] = $proselection->getPrice();
                $cont++;
            }
    // get options ids
    $optionsCollection = $_product->getTypeInstance(true)
                ->getOptionsCollection($_product);
   
    foreach ($optionsCollection as $options) {
           $id_option = $options->getId();
                }           
    // generate bundle_option array
    $bundle_option = [$id_option => $selectionArray];
    $bundle_qty = [$id_option => $selectionqtyArray];
    $bundle_price = [$id_option => $selectionpriceArray];
   
   
    $params = [
                'product' => $_product->getId(),
                'bundle_option' => $bundle_option,
                'bundle_option_qty' => $bundle_qty,
                'bundle_option_price' => $bundle_price,

Magento 2: [SOLUTION] Order confirmation email contains no FROM or FROM EMAIL address

Confirmation emails have no FROM or FROM email address 2.2.4

Going to : /vendor/magento/module-sales/Model/Order/Email/SenderBuilder.php

 Edit function configureEmailTemplate() and add this line
 $this->transportBuilder->setFrom($this->identityContainer->getEmailIdentity());
 to show like below:

 protected function configureEmailTemplate()
 {
$this->transportBuilder->setTemplateIdentifier($this->templateContainer->getTemplateId());
$this->transportBuilder->setTemplateOptions($this->templateContainer->getTemplateOptions());
$this->transportBuilder->setTemplateVars($this->templateContainer->getTemplateVars());
$this->transportBuilder->setFrom($this->identityContainer->getEmailIdentity()); //the below are commented
//$this->transportBuilderByStore->setFromByStore(
// $this->identityContainer->getEmailIdentity(),
// $this->identityContainer->getStore()->getId()
// );
 }

Its a simple fix and its work perfectly.
