The implementation of interpolation grid techniques at NNLO and their subsequent application to the extraction of the strong coupling constant α s
presented in Ref.  are based on the calculation in the framework [2,3,4]. An implementation error was found in this calculation  that altered the predicted cross sections for the DIS process at NNLO. While technical aspects and equations remain unchanged, reported numerical values and the extracted value of α s
are affected. Updated figures, tables, and numbers quoted in the main text that have changed are provided. Numbering of sections and figures is as in Ref. .
