Serde still causing errors even after 1.0.212

[sffc]

Serde 1.0.211 broke some call sites described in #2844 and later fixed in #2845

I believe it is still broken. The number of errors is reduced, but I am still seeing one:

...
  Downloaded serde_derive v1.0.212
...
error[E0425]: cannot find value `__e` in this scope
