The message says that it could not find metadata for "openai/aws/claude-3.5-sonnet". A few lines later it suggests exactly that "openai/aws/claude-3.5-sonnet".

I double checked that the file exisits and the entry is there.

  "openai/aws/claude-3.5-sonnet": {
    "max_tokens": 200000,
    "max_input_tokens": 200000,
    "max_output_tokens": 4096,
    "input_cost_per_token": 0.000003,
    "output_cost_per_token": 0.000015,
