Describe the bug

I am using Amplify android for authentication in my application. I signed in using Amplify.Auth.signIn but when I close application and start again and call Amplify.Auth.fetchAuthSession I get below error AWSCognitoAuthSession(isSignedIn=false, identityIdResult=AuthSessionResult{value=ap-southeast-1:xxxxx-xxxx-xxxxxxxxxxxx, error=null, type=SUCCESS},. Also I use AWSSdk for awssigner authorization `class AwsInterceptor( private val awsCredentials: CognitoCachingCredentialsProvider, // AWS credentials private val serviceName: String, // Service to sign requests for (e.g., execute-api) region: String // AWS region (e.g., ap-southeast-1) ) : Interceptor {

private val signer: AWS4Signer = AWS4Signer()

init {
    signer.setServiceName(serviceName)
    signer.setRegionName(region)
}

override fun intercept(chain: Interceptor.Chain): Response {
    val signedRequest = signRequest(chain.request())
    return chain.proceed(signedRequest)
}

@Throws(IOException::class)
private fun signRequest(request: Request): Request {
    val builder = request.newBuilder()
    val awsRequest = DefaultRequest<Any>(serviceName)
    builder.addHeader("x-api-key", "I513UYRoQT4SNGrHDzWFS6wfKw1e9b9J9UaT24vk")
    // Set endpoint and add query params
    val url = setEndpoint(builder, awsRequest, request.url)
    setQueryParams(awsRequest, url)

    // Set HTTP method
    setHttpMethod(awsRequest, request.method)

    // Set body (if any)
    setBody(awsRequest, request.body)

    // Sign the request with AWS4Signer and credentials
    signer.sign(awsRequest, awsCredentials.credentials)

    // Apply signed headers to the request
    applyAwsHeaders(builder, awsRequest.headers)

    return builder.build()
}

private fun setEndpoint(
    builder: Request.Builder,
    awsRequest: DefaultRequest<Any>,
    url: HttpUrl
): HttpUrl {
    val canonicalUrl = ensureTrailingSlash(builder, url)
    awsRequest.endpoint = canonicalUrl.toUri()
    return canonicalUrl
}

private fun setQueryParams(awsRequest: DefaultRequest<Any>, url: HttpUrl) {
    for (paramName in url.queryParameterNames) {
        awsRequest.addParameter(paramName, url.queryParameter(paramName))
    }
}

private fun setHttpMethod(awsRequest: DefaultRequest<Any>, method: String) {
    val methodName = HttpMethodName.valueOf(method)
    awsRequest.httpMethod = methodName
}

@Throws(IOException::class)
private fun setBody(awsRequest: DefaultRequest<Any>, body: RequestBody?) {
    if (body == null) return

    val buffer = Buffer()
    body.writeTo(buffer)
    awsRequest.content = ByteArrayInputStream(buffer.readByteArray())
    awsRequest.addHeader("Content-Length", body.contentLength().toString())
    buffer.close()
}

private fun applyAwsHeaders(builder: Request.Builder, headers: Map<String, String>) {
    for ((key, value) in headers) {
        builder.header(key, value)
    }
}

private fun ensureTrailingSlash(builder: Request.Builder, url: HttpUrl): HttpUrl {
    val lastPathSegment = url.pathSegments.lastOrNull()
    if (!lastPathSegment.isNullOrEmpty()) {
        val updatedUrl = url.newBuilder().addPathSegment("").build()
        builder.url(updatedUrl)
        return updatedUrl
    }
    return url
}

}`

Hi @Mehdi-android, thank you for submitting the issue! One of our team members would investigate it as soon as possible. In the meantime, could you share your logs as well as session details before and after relaunching the app? This will help our investigation.

Actually issue was I was using amazonawscore as well as amplify sdk, which was causing the issue. I am only using amplify now which resolved the issue.
