Flatten: Throws error due to end-of-file in api response

Hello,
I have been using flatten to look at the Resonate protocol's contracts and found a runtime error that feels out of place.
Reproducible command
sol2uml flatten --network fantom 0x1a5c2ee3fb7fe4a2c2e42474a3657c71f6c775cf
A few affected contracts

Looks like an issue with the latest axios release axios/axios#5346.
It works if I downgrade to v1.1.3
naddison36 commented
Fixed with release https://github.com/naddison36/sol2uml/releases/tag/v2.4.1
plotchy commented
On a fresh uninstall->reinstall, the package-lock.json still contains axios v1.2.1
Does the ^ in the semver versioning of ^1.1.3 cause this to default to v1.2.1?
naddison36 commented
you are correct. Pls try https://github.com/naddison36/sol2uml/releases/tag/v2.4.2
