The following is a checklist to take note of, before adding items to the list of components for deployment.

1. Check the correct API name.

2. Check the metadata type.

To help this process, we can use workbench Metadata Types & Components to check if the component's API name and metadata type is correct:

Then select the metadata type, and find the component's 'fullName' from the list to confirm that the API name given in the component list is correct:

If the metadata type or the component itself cannot be found in the list for the metadata type, then please double check if either the API name or the metadata type is correct. Consult with the SME if the component still can't be found.

Note that some metadata such as Lightning Email Template may not be visible through the workbench metadata list but still can be retrieved if the metadata type and API name are correct.
