Getting a sudden error while initialisation of the Swagger.

Swagger Client version 3.9.0

[olemoign]

Getting same error here.

[alecf]

I also started getting this, after updating some npm packages... not such which one though

[alecf]

the problem is version 2.2.0 of fast-json-patch!

[shockey]

Confirmed, installing fast-json-patch@2.2.0 locally is blowing up Swagger Client tests.

I'm going to dig in a bit before taking action, but I'll most likely push out a new Swagger Client patch version that pins fast-json-patch@~2.1.0 today.

[shockey]

I've just published swagger-client@3.9.1 directly on top of 3.9.0 (i.e., this release doesn't include the housekeeping items currently on master). Diff here. This version of Swagger Client is pinned to the tighter range, fast-json-patch@~2.1.0, that I mentioned earlier.

This should solve the issue for now, but I'll file an upstream bug with fast-json-patch to let them know it appears an incorrectly-set __esModule flag is causing issues.

Thanks for the help here @jaliph @olemoign @alecf!

[olemoign]

Man, 100% of the credits to you. :)

[jaliph]

@shockey Thanks for the quick resolution

[shockey]

FYI, I've opened the upstream issue with fast-json-patch: Starcounter-Jack/JSON-Patch#233
