Cannot compile with feature "Script"

I want to compile a binary for a smart meter.

#ifndef USE_SCRIPT
#define USE_SCRIPT
#endif
#ifndef USE_SML_M
#define USE_SML_M
#endif
#ifdef USE_RULES
#undef USE_RULES
#endif

But I get an error every time I define my custom features.

I narrowed the issue down to the script feature.

These are the log messages that seem to be important:

Am I doing something wrong? Can anybody reproduce this issue? Do you need more information?

Thanks.

Not a Tasmota issue. Webinterface is enabled by default in Tasmota setup. It should be enabled always by default. There are only a few setups possible without webinterface.

[benzino77]

Should I create an issue over there?

Ask them on discord channel. There is a lot of people ready to help.
