Caught an error from batch translate

[leons1767]

Hi @AidanWelch

I caught a new error from the below codes.

trInput is an array for batch translation.

It doesn't happen all the time, maybe 1 out of 4 or 5 times. Even when all the variable values are exactly the same for all the 4 or 5 times.

    const translation = await translate(trInput, {from: userLanguage, to: addHelperLanguage && helperLanguage, autoCorrect: true})
                                .catch((error) => {
                                    console.error('translate| translate-google-api-x error: ', error.message)
                                    throw error
                                });

Error caught in below

translate| translate-google-api-x error:  Cannot read properties of null (reading '1')

I'm able to replicate a similar error by spamming thousands of requests in quick succession responding with:

I would say just try varying requests, as one of the test unit tests is 1000 requests and it doesn't have any issues. Also don't send 1000+ at the exact same time. You can also try using a proxy.

Thanks @AidanWelch

I only sent 2 identical sentences in the array, to translate to different languages. I guess I will need a retry bloc.

[AidanWelch]

Huh, that is weird maybe Google is changing their rate limits. You can also try calling with forceBatch: false if you're just trying individual strings. So that it at least spreads out your requests across endpoints.

I get a similar issue with an empty string.

[AidanWelch]

I get a similar issue with an empty string.

Interesting, that doesn't seem breaking though

[abhinandanudupa]

Yes, it is not breaking but it can be hard to figure the reason. So, I have raised a PR which can help in such a situation for this situation. It can be helpful when the user unknowingly inputs empty strings.

[AidanWelch]

Can you see if updating to v10.6.5 helps with the error logging of your issue?

[AidanWelch]

The error logging works, but it seems like batch requests are failing too often, it may be to do with the init. Will investigate
