In solidity code I have function addPhase and it works well. The code below also works well

for (let j = 0; j < companies[i].phases.length; j++) {
    transactions.push(
        this.contract.addPhase(
            companies[i].phases[j].start_time,
            companies[i].phases[j].prices_in_wei,
            companies[i].phases[j].prices_in_wei_ends,
            companies[i].phases[j].tokens_count,
            companies[i].phases[j].min_tokens_to_sell,
            Web3Helpers.sender_envelope(sender,10000000000)));
}

But if I try to estimate gas consumption

for (let j = 0; j < companies[i].phases.length; j++) {
    let call_data_phase = this.contract.addPhase.getData(
        companies[i].phases[j].start_time,
        companies[i].phases[j].prices_in_wei,
        companies[i].phases[j].prices_in_wei_ends,
        companies[i].phases[j].tokens_count,
        companies[i].phases[j].min_tokens_to_sell
    );
    let gas_needed_phase = Web3Helpers.web3.eth.estimateGas({
        data: call_data_phase,
        to: this.contract.address,
        from: sender
    });
    console.log("Gas estimation=" + gas_needed_phase);
    
    transactions.push(
        this.contract.addPhase(
            companies[i].phases[j].start_time,
            companies[i].phases[j].prices_in_wei,
            companies[i].phases[j].prices_in_wei_ends,
            companies[i].phases[j].tokens_count,
            companies[i].phases[j].min_tokens_to_sell,
            Web3Helpers.sender_envelope(sender,10000000000)));
}

I get error gas required exceeds allowance or always failing transaction. I use similar code for other functions and gas estimation works well. Have anyboby seen something like this and what can it be?

Has anybody seen something like this and what could it be?
