I created CSR file eidas.csr following content

    oid_section = OIDs

[ req ]
distinguished_name = dn
prompt = no

[ OIDs ]
OrganizationID=2.5.4.97

[ dn ]
O=Enable Banking Oy
L=Espoo
C=FI
OrganizationID=PSDFI-FINFSA-29884997
CN=enablebanking.com

I run the following command: openssl req -new -config eidas.conf -keyout eidas.key -out eidas.csr

and I get the following error:

problem creating object OrganizationID=2.5.4.97
140676474279104:error:08064066:object identifier routines:OBJ_create:oid exists:../crypto/objects/obj_dat.c:709:

HOWEVER, if I Change Oid declaration Line 2.5.4.97 whit 1.2.3.4 this succeeds

In newer openssl version OID 2.5.4.97 is reserved for organizationIdentifier, so you can change your eidas.conf to the following and it should work.

[ req ]
distinguished_name = dn
prompt = no

[ dn ]
O=Enable Banking Oy
L=Espoo
C=FI
organizationIdentifier=PSDFI-FINFSA-29884997
CN=enablebanking.com

Also not the values in [ dn ] section. Apparently you copied eidas.conf from https://enablebanking.com/blog/2020/01/13/how-to-generate-eidas-certificate/ and there the value were given just as an example and probably you would want to change them to describe your own organization, location and domain (although for psd2 sandboxes any values are likely to work).
