[Blockly] Contextual info 'event available' throws error instead of 'false'

[maxmaximax]

The problem

An error is thrown when a rule calls another rule and 'event available' is used as contexual info.

Rule 1:

console.info('Rule fired ... (something...)');
console.info((event !== undefined));
console.info(event.type);
rules.runRule('test_blockly_something_else', {});
console.info('Rule finished ... (something...)');

… runs Rule 2:

console.info('Rule fired ... (something else...)');
console.info((event !== undefined));
console.info('Rule finished ... (something else...)');

Log:

2025-03-01 21:14:00.815 [INFO ] [ion.script.ui.test_blockly_something] - Rule fired ... (something...)
2025-03-01 21:14:00.815 [INFO ] [ion.script.ui.test_blockly_something] - true

Expected behavior

'event available' in rule 2 should return 'false' instead of the error

Steps to reproduce

Use the Blockly I posted above.
