PicoC assistance requested - Wunderground Program - 'memory not valid'

[Tico]

I refer to this post on the German forum -

https://www.loxforum.com/forum/faqs-tutorials-howto-s/1049-howto-wunderground-api-in-programm-baustein-abfragen

or via Google Translate -

https://translate.google.com.au/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=https%3A%2F%2Fwww.loxforum.com%2Fforum%2Ffaqs-tutorials-howto-s%2F1049-howto-wunderground-api-in-programm-baustein-abfragen&edit-text=

The PicoC program runs successfully for those outputs triggered by AI2 ('Forecast Today', 'Forecast Tomorrow' and 'Forecast day after Tomorrow').

The outputs triggered by AI1 (listed below from the Loxone Log file) run successfully for one iteration. The second triggering of the AI1 input causes a 'memory not valid' error. In the log example below, it's triggered every 3 minutes.

I don't know what Loxone version the PicoC program was written for, however when importing the .loxone file from the link above, a message says "Note: The document was adjusted to be compatible with the latest version. Please save the changes!". I suspect this adjustment may be the issue (or the bug might be integral to the original file).

I'm running Loxone v7.4.4.14

I'd be very appreciative of any PicoC conversant person to cast their eye over this.
