GET requests ignored after updating Fable tool to 4.13.0
Steps to replicate
- Install SAFE template 5.0.4
- dotnet new SAFE
- dotnet tool restore
- dotnet run
- Notice that Todos get loaded
- dotnet tool update Fable (latest is 4.13.0)
- dotnet run
Expected behaviour
Todos get loaded as before
Actual behaviour
The GET request for the Todos is not fired
Additional info
Works with Fable 4.12.2 POST requests work correctly I have another demo that has multiple GET requests and they are all ignored when firing as a Cmd in Elmish
After doing some quick digging I have located the issue
https://github.com/Zaid-Ajaj/Fable.Remoting/blob/c812705fbd95097191257ff288cdab409029807a/Fable.Remoting.Client/Proxy.fs#L181
Previous behaviour in Fable 4.12.2
inputArguments.[0] on an empty array
would result in undefined serialised to [null]
New behaviour in Fable 4.13.0
inputArguments.[0] on an empty array
result in an exception Index outside the bounds of an Array
Solution
Need some conditional logic around array accessors or tryIndex to prevent the exception
