Error Occurred when use HasOne Relation

[phpMuhammed]

This is the relation between Brand and Attachment Models

// brand has one attachment
    public function attachment()
    {
        return $this->hasOne(Attachment::class);
    }

// attachment belongs to brand
	public function brand()
    {
        return $this->belongsTo(Brand::class);
    }

and this is the code in Brand Resource
HasOne::make('attachment')->inline(),

finally this is the error

@phpMuhammed The issue appears to be that you nee the HasOne field in the Attachment resource, and the BelongsTo field in the Brand resource. Try switching those and let me know if it fixes the issue.
