TypeError: Expected `input` to be a `string`, got `undefined`

[magick93]

Hello

Im trying to use openapi-client-axios to generate a TS client, however, when I try either typegen http://localhost:8080/openapi > src/modules/client.d.ts or typegen /home/magick93/Downloads/openapi_vaults > src/modules/client.d.ts I get the below error.

Looks like your OpenAPI definition is missing operationIds. Currently openapi-client-axios expects each operation to have an operationId.

Closing issue due to no activity for 30 days

Just got here after reading #24 and finding swagger2openapi.

That converter doesn't add operationIds. Not sure what can be done but wanted that documented for the next person
