Descrizione

@kwonoj we've been having a lot of success using @swc/plugin-relay so far, but it seems to sporadically fail in our CI environment. I've updated @swc/core, @swc/jest and @swc/plugin-relay but am still experiencing issues. Without @swc/plugin-relay, the tests pass every time. With @swc/plugin-relay, our Jest tests can fail in two different ways:

  1. The Jest tests run to completion, but the final results are not logged and the process never exits, causing our CI build to timeout
  2. Some tests fail with the following stacktrace. In these cases, the process often does not exit (See # 1)
 thread '<unnamed>' panicked at 'range end index 9725912 out of range for slice of length 4780000', library/core/src/slice/index.rs:73:5

Unfortunately I can't recreate this locally so I can't provide a reproduction repo for you to see it in. Hopefully something in the stack trace stands out 😄. One note, the end index 9725912 is exactly the same in all cases of this error, while the slice length 4780000 can vary.
