Hi @Dawit_Uta
I think in order to use %x which belongs to a “Custom Identifier”, you may need to configure it too.
There is a similar discussion here, which may be helpfull.

DOIs and "public URL identifier"

See the option in the DOI plugin settings, specifically the “%x” pattern. Use the pattern entered below to generate DOI suffixes. Use %j for journal initials, %v for the volume number, %i for the issue number, %Y for the year, %a for the OJS article ID, %g for the OJS galley ID, %f for the OJS file ID, %p for the page number and %x for “Custom Identifier”. Note, though, that a DOI is intended to be an opaque identifier, and generally shouldn’t be “informative”. https://www.doi.org/doi_handb…
