Source: I started writing assembly code in 1968, over the years coding for Sigma 5/7, PDP-10, TI 9900, 6502, 8080, Z80, 8086, 68000, x86, and ARM. I occasionally saw it called assembler language, but less often than assembly language.
Update: As I think about it, there is a bit more nuance to the terminology that I remembered at first. While I do recall "assembler language" and "assembler code" as being infrequently used, "assembler" by itself has often been a common usage:
"I'm writing this in assembly code."
"I'm writing this in assembler."
Those were used fairly interchangeably, even by someone like me to whom "assembler code" sounded a bit off.
So you're definitely not wrong to call it "assembler". Where you're going wrong is claiming that "assembly code" is incorrect.

If Agner Fog has no problem calling it 'assembly'[0], then neither do I.
Because they've written more applications in assembler than anyone else in the history of computing. Look at Aminet, and csdb.dk, and that's just Amiga and C=64, I haven't even included the Spectrum, Amstrad CPC, Atari ST and PC.
Absolute unbridled nonsense.
They've been using that name since 1992, and if those guys aren't "scene coders" then I've never seen one.
I never went back in the day, but pretty sure I didn't primarily interpret it as "ooh, a congregation of people".
Although assembly is machine code represented with mnemonics, they're not the same: assemblers take assembly and produce machine code.
Assembly is also the result of something that was assembled.
(which is why the tool to handle them is called objdump)
