Fix HttpError 400 "Too many text segments"

[stephenh...@u.northwestern.edu]

I am trying to translate a list of Chinese names to English but when I use q=[] I receive

googleapiclient.errors.HttpError: <HttpError 400 when requesting https://www.googleapis.com/language/translate/v2 returned "Too many text segments">

I am translating 200 for now but I need to translate about 1000 Chinese names into English.  How does one do this?  Can it be done by reading a .txt file instead of using q=[]?  Many thanks.  Steve

By "using q=[]", do you mean that you supply multiple values for q in the query, like this: q=asdfg&q=hjkl&q=qwerty&q=uiop ?

You could attempt to make multiple requests with fewer names in each request. Let me know how that goes.

Any updates on my last question? It's not clear exactly what's causing the issue here. Maybe you could supply some example requests and responses?

Hi Nick,

I am getting the same error message "Too many text segments, Domain: global, Reason: invalid" is there a limit as to how many 'q' segments you can send in one request ?

Thanks

I'm not aware of any such limitation, although it could be possible. How many segments are you sending? There's a thread which is several years old now showing some users had noted a limit at 128. You could attempt to break up the requests into smaller sizes and batch them. Let me know how that goes.

Hi Nick,

I am using python api of google translator as below:

from google.cloud.translate_v2.client import Client

client = Client.from_service_account_json(auth_json)
paragraphs = ['p1', 'p2', 'p3'...]
res = client.translate(paragraphs, target_language='zh-CN')

and get a similar error message:

error : 400 POST https://translation.googleapis.com/language/translate/v2: Too many text segments

with the length of input paragraphs list is 240 and I figure out that two other successful paragraphs's length are 89 and 33.

So it seems the magic number 128 is the limit as posted above.

However, as a commercial service, is there any document specifying this critical limit?

Thanks
