Not able to load bookmarks Tensorboard Projector programmatically

I'm running Tensorboard (tried v 2.3.0 and 2.4.1) Embedding Projector, with no issues for setting up the sprite image, the metadata and the tensors. However, the bookmarks are not loading programmatically to the page. The data seems fine, since I'm able to load the file manually on the page (either as .txt or .json).

Has anyone experienced the same issue? Any suggestions?

Thanks very much!

`` from tensorboard.plugins import projector

config = projector.ProjectorConfig()
embedding = config.embeddings.add()
embedding.tensor_path = "feature_vecs.tsv"
embedding.sprite.image_path = "BHI.png"
embedding.metadata_path = 'label_preloaded.tsv'
embedding.bookmarks_path = "bookmarks.txt" ``
