@findify/sdk: Uncaught error when `send` times out

[simonlovesyou]

Issue

We've noticed recently that findify crashes intermittently when we're trying to retrieve a smart collection, recommendations etc with the following error:

Cannot read properties of undefined (reading 'status')

I've debugged it on our end and seems like it crashes in packages/sdk/src/utils.ts#L24 when the error it catches is a "timeout error" and the error does not contain a response

err in packages/sdk/src/utils.ts that does not contain response

Steps to reproduce

Go to some website (e.g. matsmart.se/) and navigate around and hope that the findify client .send times out. If so you should be able to see the error in the web developer console.

Versions

• @findify/sdk: v2.5.9

Screenshots

Expected

That @findify/sdk can gracefully handle their errors

Actual

Errors internal to @findify/sdk propagate and are uncaught by the lib.

Suggested fix

Properly type "err" and check if response exists on err before reading response

Any eyes on this from the maintainers? @wolff95 ?

Hello Simon, sorry for the late response!

I'll investigate on this and let you know, but so far, couldn't reproduce it.
Anyhow I'll better handle the error to not crash it.

Hello Simon, I have pushed a new version with a simple nullcheck.
In later iteration the error will be handled better, but this should be enough to solve your issue.

2.5.10

Let me know if it works out.
