Jon00 Datascaper compiler error on rPi/Linux

[Thorden]

Hi,
I have struggled a bit getting the Jon00 Datascraper script to run. It just returns a long error message in the log that doesn't really tell me much.
I suspected an outdatet Linux/Mono installation, so I got it all updatet to latest and greatest everything. No success, exactly same error message.

It does not create the text file or any devices, just immediately throws the error below.

Any clues? Thanks!

Looks like you are running the obsolete VBNC compiler

This should resolve the issue:

From terminal, enter:

install -p /usr/bin/vbc /usr/bin/vbnc

Thanks, Jon!
That did the trick! Would have taken me ages to figure that one out.

However, now I get this in the log (see below).
There shouldn't be any authentication to the api, at least it works just using the URL in the browser. SSL or certificate issue?

Try adding under [Grab1]

SSLMode=3072

(See page 5 in the docs).

Try adding under [Grab1]

SSLMode=3072

(See page 5 in the docs).

Site uses TLS 1.3, so I already had it at SSLMode=12288 as per the doc. Tried 3072 as well, no success.

Here is my simple .ini file, just for testing purpose for now:

OK, try the advanced SSLMode to ignore Certificate validation:

SSLMode=*3072

[jon00]

Your Pattern1 should also be:

Pattern1=JSON> 0.NOK_per_kWh

OK, try the advanced SSLMode to ignore Certificate validation:

SSLMode=*3072

Thank you so much, that did the trick!
