System.FormatException: The format of value '' is invalid.
Hello there!
I'm trying to make a request like this
#r "nuget: FsHttp"
open FsHttp
http {
POST "https://api.jspm.io/generate"
body
json ("""{
"install": [ "lodash" ],
"env": [ "browser", "module" ],
"graph":true,
"provider": "jspm"}""")
}
|> Request.send
|> Response.toText
|> printfn "%s"
the expected JSON content is the following
{
"staticDeps": [
"https://ga.jspm.io/npm:[email protected]/lodash.js"
],
"dynamicDeps": [],
"map": {
"imports": {
"lodash": "https://ga.jspm.io/npm:[email protected]/lodash.js"
}
},
"graph": {
"https://ga.jspm.io/npm:[email protected]/": {
"lodash.js": {}
}
}
}
but I get the following instead

When I use nightingale I get this log, not sure if it helps at all

Let me know if you need further information
Thank you for the issue report. Unfortunately, I cannot reproduce it. If you have further info, please share them. In my test, I use VS2022, .Net SDK 6.0.304 and a plain .fsx file with the content copied from above.
Could you omit the |> Response.toText |> printfn "%s" and just run this in FSI:
#r "nuget: FsHttp"
open FsHttp
http {
POST "https://api.jspm.io/generate"
body
json """
{
"install": [ "lodash" ],
"env": [ "browser", "module" ],
"graph":true,
"provider": "jspm"
}
"""
}
|> Request.send
This will print the request, and response + content in the FSI output - like this:

Ah yes, I forgot to include that I'm on .NET7 previews

Using a global json with .NET6 seems to work though it might be something newly introduced in .NET7

Thanks for the info. I'll investigate and see if that might be a bug in .Net 7 or if FsHttp is doing something wrong that might have been masked before...
Thanks for reporting the issue @AngelMunoz and fixing it @Samuel-Dufour :)
I've released and tested 10.0.0-preview2. See related PR and commits.
