dealing with lex web ui integration; I'm using lex api
url = https://runtime-v2-lex.us-east-1.amazonaws.com/bots/botid/botAliases/botaliasid/botLocales/en_US/sessions/Session23_/text
this api work fine on postman, I typed a simple python script and it's works fine also.
But when I tried to integrate this api with necessery authorizations into a web page using html/js
I got this error :
caught ReferenceError: AWSRequestsAuth is not defined
I even tried to reinstall AWSRequestsAuth with the command below but in vain:
pip install aws-requests-auth
** HTML page script : **
<!DOCTYPE html>
<html>
<head>
<title>Chatbot Example</title>
</head>
<body>
<h1>Chatbot Example</h1>
<form>
<label for="input">Input:</label>
<input type="text" id="input" name="input">
<button type="submit">Send</button>
</form>
<div id="output"></div>
<script>
const form = document.querySelector('form');
const output = document.querySelector('#output');
form.addEventListener('submit', (event) => {
event.preventDefault();
const input = document.querySelector('#input').value;
const payload = {text: input};
const url = 'https://runtime-v2-lex.us-east-1.amazonaws.com/bots/botid/botAliases/botaliasid/botLocales/en_US/sessions/Session23_/text';
const headers = {
'Content-Type': 'application/json',
'X-Amz-Content-Sha256': 'XXXXXXXXXXXX',

};
const auth = new AWSRequestsAuth({
accessKeyId: 'XXXXXXXXXX',
secretAccessKey: 'XXXXXXXXXXXXXX',
host: 'runtime-v2-lex.us-east-1.amazonaws.com',
region: 'us-east-1',
service: 'lex',
});
fetch(url, {
method: 'POST',
headers: headers,
body: JSON.stringify(payload),
auth: auth,
})
.then(response => response.json())
.then(data => {
const messages = data.messages.filter(message => message.contentType === 'PlainText');
const outputText = messages.map(message => message.content).join('\n');
output.textContent = outputText;
})
.catch(error => {
console.error(error);
output.textContent = 'Error: ' + error.message;
});
});
</script>

thanks for responding; I don't think so because the problem is related to the AWSRequestsAuth library that is not running correctly, although I already install it, this is what I got with pip list command : Package Version
aws-requests-auth 0.4.3
