am getting an exception com.zebra.rfid.api3.OperationFailureException on last line

override fun writeTagID(tagId: String, newId: HexString, password: HexString) {

// конфигурация взята из офф. документации https://techdocs.zebra.com/dcs/rfid/android/2-15/guide/tagwrite/

reader.Config.setAccessOperationWaitTimeout(3000)

reader.Actions.Inventory.stop()
reader.Config.dpoState = DYNAMIC_POWER_OPTIMIZATION.DISABLE

val tagData: TagData? = null
val tagAccess = TagAccess()
val writeAccessParams = tagAccess.WriteAccessParams()
val writeData: String = newId.value

writeAccessParams.accessPassword = password.value.toLong(16)
writeAccessParams.memoryBank = MEMORY_BANK_EPC
writeAccessParams.offset = 2 // offset is two for EPC ID

writeAccessParams.setWriteData(writeData)
// set retries in case of partial write happens
writeAccessParams.writeRetries = 3
// data length in words
writeAccessParams.writeDataLength = writeData.length / 4
// 5th parameter bPrefilter flag is true which means API will apply pre filter internally
// 6th parameter should be true in case of changing EPC ID it self i.e. source and target both is EPC
reader.Actions.TagAccess.writeWait(tagId, writeAccessParams, null, tagData, true, true)
}
I read the documentation. Tried increasing the timeout but still getting an exception.
