Hello,

My submission to RuTermEval competition (Track 2, Phase 2: https://codalab.lisn.upsaclay.fr/competitions/19600#participate-submit_results) keeps failing with the following error:

Traceback (most recent call last):
File "/worker/worker.py", line 323, in run
bundles = get_bundle(root_dir, 'run', bundle_url)
File "/worker/worker.py", line 180, in get_bundle

File "/worker/worker.py", line 180, in get_bundle

File "/worker/worker.py", line 171, in get_bundle

self.peek_token().start_mark)
ParserError: expected '', but found '{'
in "/tmp/codalab/tmpM4mRoO/run/input/ref/metadata", line 2, column 1

Is it my fault? If so, how can I solve it?
I'm using Google Chrome 131.0.6778.265 (64-bit)
Thank you for help!
