Cannot instantiate interface Magento\InventoryReservationsApi\Model\GetReservationsQuantityInterface

[SrLucasM]

Fatal error: Uncaught Error: Cannot instantiate interface Magento\InventoryReservationsApi\Model\GetReservationsQuantityInterface in MAGE_ROOT/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php on line 50

With the modules enabled and disabled I ran the 'hamster wheel' troubleshooting cycle. 

Steps were taken so far: (not in this order)
• Flushed cache
• Removed the generated/code folder
• ran s:up and s:di:c
• disabled the following:

List of disabled modules:
Magento_InventoryReservations
Magento_InventoryReservationCli
Magento_InventoryReservationsApi

This occurred after upgrading from 2.2.8 to 2.3.1, saw other issues and upgraded to 2.3.2.

Enabled below modules if they are disabled.

Magento_InventoryDistanceBasedSourceSelection
Magento_InventoryDistanceBasedSourceSelectionAdminUi
Magento_InventoryDistanceBasedSourceSelectionApi
Magento_InventoryElasticsearch
Magento_InventorySetupFixtureGenerator

If it will not work then enabled all Magento_Inventory related modules and check.

[mallikajai5922]

Please enable all the modules related to Magento_Inventory  in  app\etc\config.php

and run the below command :-
rm -rf generated
rm -rf var/*
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento setup:di:compile

Hello SrLucasM,

The error occurs after upgrading Magento from 2.2.8 to 2.3.1, and you haven't overridden the interface for the di.xml class in the file. The error can also appear by disabling or enabling the modules directly in app/etc/config.php. 

Therefore, to fix the "Cannot instantiate interface Magento\InventoryReservationsApi\Model\GetReservationsQuantityInterface" error, follow the steps below:

CLI (Command Line Interface) is a text-based user interface that views and manages files. Magento has a default CLI command.

•  Firstly, run the below command,

bin/magento setup:upgrade

• The above command clears compiled code, the cache and updates components.
• Now, check if the following two files exist:

1. app/etc/env.php > Magento 2 stores the database credentials, backend URL, enabled cache types, etc.
2. app/etc/config.php > It contains the list of installed modules, themes, language packages, and shared configuration settings.

• Now, check the redis connection information and database settings credentials are proper.
• Lastly, Re-run the below command; if it's correctly set,

bin/magento setup:upgrade

• If you're using redis run,

redis-cli flushall

• Or, run the following commands,

Clear generated

Clear: 

var / cache

Enable magento modules:

php bin/magento module:enable --all

Compile DI

• The command 'bin/magento setup:di:compile' develops DI configuration and all missing classes that can be auto-generated,

php bin/magento setup:di:compile

If you still encounter the same error, you can run the following command to fix the issue,

php -dmemory_limit=-1 bin/magento setup:di:compile

• An -dmemory_limit = -1 option allows you to run PHP in the CLI without memory limits. You can also change the memory_limit setting.

I hope the above-given fix helps you to fix the Cannot instantiate interface in Magento. However, if the issue persists, you can update it here.
