google.protobuf.json_format.MessageToJson() including_default_value_fields argument has been deprecated and removed since protobuf v5.26. need to use `always_print_fields_with_nopresence instead.

temporary fix is to just downgrade protobuf to 4.25

@busFred TKS! Downgrading protobuf to 4.25 works.

Thanks for flagging this.

Looks like the new parameter was added less than 2 months ago in protocolbuffers/protobuf#15703, so it would only be present in very recent versions of protobuf dependencies, which might be a bit restrictive.

For now, I'll add a restriction for the protobuf dependency to be < 5.0.0, and eventually we can update it to use the new parameter when we need to bump this dependency again for some reason.

@arcra Adding the upper bound like that is not really a great solution, because any reasonable solver with a constraint on protobuf>=5 will just go ahead and backtrack from tensorboard v2.17.0 to v2.16.2, and then remain broken.

A more compatible way to solve this is detect protobuf version and fix the call into json_format.MessageToJson conditionally depending on protobuf 4.x or 5.x.
