Not supported operator: {operator}

Error message

Not supported operator: {operator}

What it means

ValueError from Switch's condition evaluation (after the ≥/≤ branches shown). When none of the implemented operators match — contains, not contains, start with, end with, empty, not empty, =, ≠, >, <, ≥, ≤ — the fall-through raises 'Not supported operator'.

Solutions

1. Pick the operator from the Switch UI dropdown so the canonical token is stored.
2. If writing DSL, restrict operators to: contains, not contains, start with, end with, empty, not empty, =, ≠, >, <, ≥, ≤.
3. Replace '>=' with '≥' and '<=' with '≤' in existing conditions.

Example fix

// before
{"operator": ">=", "value": 10}

// after
{"operator": "≥", "value": 10}

SWITCH_OPS = {'contains', 'not contains', 'start with', 'end with', 'empty', 'not empty', '=', '≠', '>', '<', '≥', '≤'}
for cond in switch_param.conditions:
    assert cond['operator'] in SWITCH_OPS, cond['operator']

def is_switch_operator(op: str) -> bool:
    return op in {'contains', 'not contains', 'start with', 'end with', 'empty', 'not empty', '=', '≠', '>', '<', '≥', '≤'}

try:
    switch._invoke()
except ValueError as e:
    if 'Not supported operator' in str(e):
        # replace with a supported operator token and re-run
        ...

When it happens

Trigger: A Switch condition whose operator is anything outside the SwitchParam.operators list: typos like 'starts with', '>=' instead of '≥', 'equals' instead of '=', or a localized label. Note Switch uses '≥'/'≤' Unicode forms, not ASCII '>='/'<='.

Common situations: Hand-editing canvas DSL with ASCII comparison operators; copying conditions from the Categorize or Loop components which use different operator vocabularies; templates authored against an older operator set.
