How can I update the lock file?

[fmeum]

@mering Run bazel mod deps in tests/bcr.

[fmeum]

I sent out #1673 to simplify future contributions.

[mering]

@fmeum I already tried the command from the error message:

$ cd tests/bcr
$ bazel mod deps --lockfile_mode=update
Starting local Bazel server and connecting to it...
FATAL: bazel crashed due to an internal error. Printing stack trace:

[fmeum]

@mering Which version of Bazel are you using? .bazelversion for tests/bcr specifies 6.4.0, which should be used automatically if bazel is Bazelisk (recommended setup).

[mering]

@fmeum thanks for the hint. I was using 6.3.2 and when using Bazelisk it worked!

[mering]

Tests are passing now.
