What does this mean?
An input has been found using inputmode="decimal".
For example:
<label for="amount">How much do you want to pay?</label>
<input type="text" id="amount" inputmode="decimal">

How to fix
Avoid using the decimal value. Leave the type set as plain text.
For example:
<label for="amount">How much do you want to pay?</label>
<input type="text" id="amount">
