try postman-to-k6 PostmanCollection.json -o k6-script.js

[jhewitt]

It gives me the same error, I suspect it is erring on the key: image[] type: file src:[] in the body? The body of this working postman script is a multipart form with two key/value pairs, the first is a json message and the second is an array of image files being uploaded.

Thank you for bringing this to my attention! Will have a look at it and get back to you.

[odetolataiwo]

is there any update on this yet?

[simskij]

Sorry, I've been completely swamped so not yet unfortunately. 😅

Apologies for the inactivity on this project.

Due to the inability to properly support this project, the k6 team has decided not to continue its development. The primary reason is that k6 scope has grown significantly with the launch of k6 extensions. The team is prioritizing extending k6 capabilities over the converters.

We suggest you post your issue at api-deck/postman-to-k6. The project is active and maintained on this fork.
