Claim for status credits from SQ codeshare flight?

[SCM]

Hello

I recently did a SYD -> MUC via SIN on SQ ticket. I got 3/4 flights SCs awarded within 2-3 days of each flight, however one of the 4 flights was actually operated lufthansa as a codeshare with an SQ code (SQ2202), and I didn't get anything for this one. I put in the request for missing points/credits and it got resolved with "Error No: 053".

I just wanted to see if anyone knows what this means, and if there's anything else at play - for example, is it the case maybe that this flight is not eligible for SCs/points because it was operated by a partner of SQ via codeshare or something.

Otherwise, the only other question I had is what does the "E-Ticket number" mean when making a claim for missing points? I left it blank as it said optional and I couldn't find it on the ticket - does it mean the booking number or something else?

Thanks
