I was having same issue (same error message) on my LANDO local instance.
Here is my file structure i.e
'docroot' folder has drupal core files/folders.
I was using composer to install drush (composer require drush/drush) at this path 'My-Project/composer.json' which executes other drush ...
I had the same error using a simple vanilla 9 version of Drupal, when using my computer's drush to run the site-install command.
I overcame this problem by requiring drush in the project and using it.
$ drush si
Error: Call to undefined method GuzzleHttp\Utils::chooseHandler()
$ composer require drush/drush
$ ./vendor/bin/drush si
You need to provide a value for the lcia_id key.
In your Feeds Type mapping, we can see that the entity's ID (nid) is mapped to the JSON file's lcia_id, but, in your sample JSON file, the lcia_id value is missing.
You could also consider using Feeds Tamper to set a default value when no value is available for lcia_id. Here is an example of how to use it.
