FRED: Failed to open [...] HTTP/2 stream 1 was not closed cleanly

[pbarill]

Noticed this since last week:

> getSymbols(Symbols="CPIAUCSL", src="FRED")

Error in getSymbols.FRED(Symbols = "CPIAUCSL", env = <environment>, verbose = FALSE,  : 
  Unable to import “CPIAUCSL”.
cannot open the connection
In addition: Warning message:
Failed to open 'https://fred.stlouisfed.org/graph/fredgraph.csv?id=CPIAUCSL': HTTP/2 stream 1 was not closed cleanly: INTERNAL_ERROR (err 2)

I'm in a country that has rather unusual internet filtering. Yet with VPN it doesn't go away. This still works, which rules out a BLS-style anti-robot policy.

wget https://fred.stlouisfed.org/graph/fredgraph.csv?id=CPIAUCSL

I'm on quantmod 0.4.28.

@ethanbsmith could this be related to #449?

[ethanbsmith]

dont think so. the 504 errors stopped for me a few days ago, and i am unable to reproduce this error on my setup. the download is just using read.csv(curl::curl(URL), na.strings="."), so other than the curl connection nothing special going on here

[ethanbsmith]

just tried read.csv("https://fred.stlouisfed.org/graph/fredgraph.csv?id=CPIAUCSL") and it works fine.
so, im not quite sure why we're using curl here. also if we remove the curl connection, i THINK the standard r timeout will be applied, eliminating the need for 449

[joshuaulrich]

I don't know why we're using curl here either. You'd have to ask the person who made commit 1739987. ;-)

I think we're using curl in every other getSymbols function though, so I'm not inclined to break with that consistency.

[ethanbsmith]

lol.

there was one source that didnt work w/o curl. i really should have commented that it was needed there, as i dont remember which.
probably added it to the others for consistency. Emerson prolly having a good laugh.

I tried a few more things. I had the latest quantmod, but not the latest curl package. Once it was updated (on a Windows instance), the problem above disappeared. Could be marked closed, but rather unusual that curl would "expire" all of a sudden.

I have the latest curl package (7.0.0) installed, but I still have the same problem :

curl::curl_download("https://fred.stlouisfed.org/graph/fredgraph.csv?id=DGS1", "test",)
Error in curl::curl_download("https://fred.stlouisfed.org/graph/fredgraph.csv?id=DGS1",  :

using a R kernel in aws, I am unable to downoad data using quantmod. I have switched from older R version (4.4.1) to a newer version (4.5.1), and still am unable to get data. Any help would be appreciated!: quantmod::getSymbols.FRED('INFECTDISEMVTRACK',
env=globalenv(),
type="xts") “Failed to open 'https://fred.stlouisfed.org/graph/fredgraph.csv?id=INFECTDISEMVTRACK': HTTP/2 stream 1 was not closed cleanly: INTERNAL_ERROR (err 2)”
