related_queries NULL, data is not loaded

[pricerices]

hi,

The scrapping process is working properly. But related_queries data is not loaded (NULL).

I check Google Trends website manually and it shows keywords as usual.

could you solve this or is it from google side?

thx

Please provide a reproducible example.

I run this:

gtrends(c("what","where","when","who","why"), geo = "", cat = "0", time = "now 7-d")

and as simple as:

gtrends("what")

What happens when you run the known working example from the README.md and documentation?

[pricerices]

I can't get related_queries data. This happened since 5 days ago.

[pricerices]

for more detail example, I run this:

allcat <- gtrends(c("what","where","when","who","why"), geo = "", cat = "0", time = "now 7-d")

allcatrq <- allcat$related_queries %>% filter(related_queries == "rising") %>% select(value)

and the error result in console:

Error in UseMethod("filter") : no applicable method for 'filter' applied to an object of class "NULL"

Experiencing this for the first time. Even though keywords/related_queries appear normally in google trends web.

I can confirm with a test query. We don't seem to be getting that data back even though the web interface has it for the same query. :-/

I will take a look tomorrow. Likely something changed in they payload options.

Just did a quick search and there are not much difference between us and Google Trends

[ins] r$>   waldo::compare(fromJSON(p1), fromJSON(p2), x_arg = "gtrendsR", y_arg = "web")

I am following this thread since (I guess) it is connected to my problem. I am having trouble downloading data from GT through gtrendsR, results are always empty while when I am doing the exact same query with pytrends I am getting the results with no problem. I checked with some colleagues of mine and they have the same problem.

Just as an example, where I am having NULL as result:

library(gtrendsR)

gt_data <- gtrends(
  keyword = "Taylor Swift",         
  geo = "US",               
  time = "today 12-m"        
)

head(gt_data$interest_over_time)

As previously said, this is not something easily fixable, as it appears that Google knows that we are not using the official web page and thus seems to block some content (#465 (comment)).

[cmp-nct]

there is more happening on browser side
When the /api/explore request is made then they send a 23kb POST object in addition to the json encoded request.
It starts like this FEWyJzZXRva2VuIiwiMDNBRmNXZUE2ZTBUaEE1X1Q

Looking a bit deeper, this is a slightly obfuscated base64 string.
If you remove the first two characters, base64 decode it then it becomes a json object ["setoken","03AFcWeA6e0ThA5.....

So it appears that google has sneaked in a huge token in addition to the small token.

Update:
It's probably google recaptcha v3 data, I guess this is dead without using a full browser in the future.

[PMassicotte]

Nice detective work. It looks like it won't be easy to fool Googl.

[pricerices]

Is it work again for today?

[PMassicotte]

What do you mean by "for today"?

[pricerices]

I just started using gtrendsr again today after a long break. The gtrendsr scrapping function for related_queries works as before as I wrote this issue.
