Evaluate Value at Each Step of a Chained Promise and Break Out of Promise

I have the following chained promise. At each step, I need to evaluate if the returned value is not null. I can add an if else condition at each step, but I was wondering if there is a more concise way of doing this. Also, how can I break out of the chain if the value is null at any step?

       axios.post('/api/login', accounts)
        .then((response) => {
          this.nonce = response.data
          return this.nonce
        }).then((nonce) => {
          let signature = this.signing(nonce)
          return signature
        }).then((signature) => {
          this.verif(signature)
        })
        .catch((errors) => {
          ...
        })

Answer

You break out of the promise chain by throwing an error:

       axios.post('/api/login', accounts)
        .then((response) => {
          this.nonce = response.data
          return this.nonce
        }).then((nonce) => {
          if (!nonce) throw ("no nonce")
          let signature = this.signing(nonce)
          return signature
        }).then((signature) => {
          if (!signature) throw ("no signature")
          this.verif(signature)
        })
        .catch((errors) => {
          ...
        })
