Seems like it is huggingface issue, I found a similar issue here

curl https://huggingface.co/BAAI/bge-large-en-v1.5/resolve/main/1_Pooling/config.json returns Entry not found, although config exists in repo

But for another models config.json is available by the same path

For example there is an available config for bge-large-en-v1.5: https://huggingface.co/BAAI/bge-large-en-v1.5/resolve/main/1_Pooling/config.json
