LotusScript NotesHTTPRequest Get Method Issue

Question

I am trying to access an API using the REST feature. But I can't retrieve the data.

Here the code

Dim Session As New NotesSession        
Dim ret As Variant
Dim URL As String
Dim headers As Variant
Dim webRequest As NotesHTTPRequest
Set webRequest = session.createhttprequest()

URL = "https://www.meteoblue.com/en/server/search/query3?query=basel"

ret  = webrequest.Get(URL)

Messagebox ret

I already solved my previous problem with this solution, but I have another error now. When I run this code, I get the following error (The problem is with "ret"):

Type mismatch in method OP_CHECK_TOS_BYVAL : BYTE found, Unknown expected

Does anyone have any idea what the problem is?

Error handler? Please add an error handler to see the LINE where this error occurs... This line Messagebox ret -e.g.- cannot work because Messagebox expects a string and not a variant... — Torsten Link
ask HCL for why they decided to go with that implementation, I have no idea... — Torsten Link

I repeat myself like a broken record: Add error handler to EVERY LINE OF CODE.

In your example you have exactly 4 lines of code where something can go wrong. And nevertheless you can't find out, which of the 4 lines causes the error if you don't use error handling (of course you could by using the debugger, but this is another story...).

Without an error handler I can only guess, that your error comes from this line:

Messagebox ret

ret is defined as Variant and the help of the function tells you, that it will return a byte array:

Return value Variant

Returns Variant content as JSON UTF8 byte array. Use the preferstrings property to return Unicode rather than UTF8 byte array.

But Messagebox expects a String as parameter --> Type mismatch...
