failed to open json report file

[alexgocariq]

Have the following version of the artillery: `VERSION INFO:

Artillery Core: 2.0.0-18 Artillery Pro: not installed (https://artillery.io/product)

Node.js: v18.0.0 OS: darwin`

Ran test and generated json file. Start report viewer and loaded the file, got this error on UI. Error loading report file. Please verify the json file is complete.

I changed the utilities mapper.ts to the following and it is working with artillery v2. Updated to include data label parsing fix

Thanks for fixing the problem, when it will be available?

I also have the same problem with:

Artillery Core: 2.0.0-20
Artillery Pro:  not installed (https://artillery.io/product)

Node.js: v16.13.1
OS:      win32

and the above fix did not work.

It appears this error occurs when the request times out and returns a ETIMEDOUT error.

I was able to get my reports to load by updating the _mapToLegacyLatency function in mappers.ts

`const _mapToLegacyLatency = (src_in) => { const src = src_in.summaries

const vals = src[Object.keys(src)[0]] || null;

return { min: vals ? vals.min : 0, max: vals ? vals.max : 0, median: vals ? vals.median : 0, p50: vals ? vals.median : 0, p95: vals ? vals.p95 : 0, p99: vals ? vals.p99 : 0 }; };`
