Attempted to create, modify or delete an instance of field with name field_icon on entity type node when the field storage does not exist.....

Hi Aman,

Thank you for reporting this issue! I will look into it.

Hmm, I'm not getting any errors when I try to reproduce this. I've tried reinstalling on an existing site, and installing on a clean Drupal installation. I'll go through the stack trace, to see if I can find a way to reproduce this

Alright, I've managed to force this to be reproduced. Here's what I did:

• Install the module
• Create an icon field
• Export the configuration
• Delete the file "field.storage.node.field_icon.yml"
• Remove some logic in the config importer to ignore all import errors and do it anyways
• Import the broken config
• Observe the same error

My conclusion is the following:
For some reason, your Drupal installation failed to create the field storage after creating the field. At this point, I do not know why this is. I'm not ruling out that this module is causing the issue, but I believe it to be another factor.

What you might want to try, is manually importing a "field.storage.node.field_icon.yml" file to see if that solves the issue. I've provided one (without a UUID, so it should be fine to import) for you to try. If this doesn't solve your error, at least it gets us a step further :).

Note: the file has been renamed by Drupal.org, so you want to remove the underscore after "node" from the filename before importing

Hi Aman,

Since I've not heard anything back, I'm going to close the issue. If my previous comment did not help you, please feel free to create a new issue.

I am having the same issue in Drupal 11. In which directory the file field.storage.node_.field_icon.yml needs to be created?
