Required gclidDateTimePair for conversion value restatement

[Veronika Miklínová]

We are sending updates of values using request  POST https://googleads.googleapis.com/v20/customers/{customerId}:uploadConversionAdjustments. Until recently, we were able to update value using orderId as conversion identifier. Now we receive the error "The required field was not present., at conversion_adjustments[0].gclid_date_time_pair.gclid". Did anything change regarding the required parameters for conversion adjustment? According to the documentation there was no change.
