Hello everyone,
I have a problem with a POST Data qraphql request.

[{“operationName”:“mySubscription”,“variables”:{},“query”:“query mySubscription {\n me {\n id\n subscriptionToDisplay {\n id\n type\n startDate\n currentBillingPeriodEndDate\n formula {\n id\n amount\n recurring\n period\n periodUnit\n displayedFormerAmount\n displayedPercentageReduction\n description {\n id\n …BaseTranslation\n __typename\n }\n __typename\n }\n recurring {\n isCancelled\n freeTrialEndDate\n __typename\n }\n appliedDiscounts {\n stripeCoupon {\n id\n percentOff\n amountOff\n duration\n durationInMonths\n __typename\n }\n __typename\n }\n __typename\n }\n freeDays {\n …FreeDaysInfoFragment\n __typename\n }\n __typename\n }\n}\n\nfragment FreeDaysInfoFragment on FreeDaysInfo {\n availableSum\n __typename\n}\n\nfragment BaseTranslation on Translation {\n id\n localized\n __typename\n}\n”}]

I tested with double \ and without \n and always got the same result.
Error code 404 with this message.

<head><title>404 Not Found</title></head>
<body>
<center><h1>404 Not Found</h1></center>

Thank you for your help.

Remove “\n”

[{“operationName”:“mySubscription”,“variables”:{},“query”:“query mySubscription { me { id subscriptionToDisplay { id type startDate currentBillingPeriodEndDate formula { id amount recurring period periodUnit displayedFormerAmount displayedPercentageReduction description { id …BaseTranslation __typename } __typename } recurring { isCancelled freeTrialEndDate __typename } appliedDiscounts { stripeCoupon { id percentOff amountOff duration durationInMonths __typename } __typename } __typename } freeDays { …FreeDaysInfoFragment __typename } __typename }}fragment FreeDaysInfoFragment on FreeDaysInfo { availableSum __typename}fragment BaseTranslation on Translation { id localized __typename}”}]
