serde_json 1.0.37

on Rust Cargo

Work around a compounding error message bug when using serde_json in combination with erased-serde (dtolnay/erased-serde#21) that resulted in error messages like:

"trailing comma at line 32 column 41 at line 32 column 41 at line 33 column 37 at line 34 column 33 at line 35 column 29 at line 36 column 25 at line 36 column 25 at line 36 column 25 at line 36 column 25"
