🐛 fix runtime msg

[prashantgupta24]

Description

Earlier, the error showed up as

RuntimeError: Warmup shape [4, {shape['prompt_length']}, {shape['new_tokens']}] results in a maximum sequence length of {max_seq_len} which is longer that what the model supports ({max_model_len})

After this fix, it shows up correctly:

RuntimeError: Warmup shape [4, 128, 20] results in a maximum sequence length of 148 which is longer that what the model supports (128)

👋 Hi! Thank you for contributing to vLLM support on Spyre.
Just a reminder: Make sure that your code passes all the linting checks, otherwise your PR won't be able to be merged. To do so, first install the linting requirements, then run format.sh and commit the changes. This can be done with uv directly:

uv sync --frozen --group lint --active --inexact

Or this can be done with pip:

uv pip compile --group lint > requirements-lint.txt
pip install -r requirements-lint.txt
bash format.sh

Now you are good to go 🚀
