Description utostan 2019-03-11 21:12:25 UTC
While attempting to create a load test for a client, a post request to a critical endpoint failed due to JMeter converting "\\\" to "\\" in the post's body data. After the conversion, JMeter sends an invalid JSON to the server and it responds with 400 Bad Request.

The client has a really weird (bad) endpoint where it accepts json in json in json which seems to throw off JMeter parser.

Body Data in HTTP Request (POST):

{"order":"{\"id\":0,\"order_date\":\"3/8/2019\",\"order_data\":{\"items\":[{\"id\":1876318,\"quantity\":1,\"name\":\"Air Filter\",\"price\":8.54,\"retail_price\":8.54,\"msrp\":0.0,\"price_level\":{\"price_level_id\":1,\"price_level\":\"RETAIL\",\"retail_multipler\":1.00,\"description\":\"Regular retail\",\"price_type\":{\"price_type_id\":1,\"price_type\":\"Regular\",\"label\":\"\"}},\"is_hazmat\":false,\"is_accessory\":false,\"oversize_category_id\":null,\"oem_number\":\"W10311524\",\"image_url\":\"https://www.redacted.com/dbImages/i/00004039/Air-Filter-W10311524-01215703.jpg\",\"quantity_by_dc\":[{\"id\":1,\"quantity\":0},{\"id\":2,\"quantity\":0}],\"repair_time\":null,\"repair_savings\":null,\"skill_level\":1,\"labor_hours\":null,\"prodcut_categories\":[{\"id\":1,\"name\":\"Appliances\"}]}],\"email\":\"${email}\",\"billing_address\":{\"first_name\":\"${first_name}\",\"last_name\":\"${last_name}\",\"street1\":\"2600 S River Rd\",\"street2\":\"\",\"city\":\"Des Plaines\",\"state\":\"IL\",\"country\":\"US\",\"zipcode\":\"60018\",\"phone\":\"1231231234\",\"ext\":\"\",\"business_name\":\"\",\"is_business_address\":false,\"is_po_box\":false},\"shipping_address\":{\"first_name\":\"${first_name}\",\"last_name\":\"${last_name}\",\"street1\":\"2600 S River Rd\",\"street2\":\"\",\"city\":\"Des Plaines\",\"state\":\"IL\",\"country\":\"US\",\"zipcode\":\"60018\",\"phone\":\"1231231234\",\"ext\":\"\",\"business_name\":\"\",\"is_business_address\":false,\"is_po_box\":false},\"shipping_choice\":{\"shipping_option_id\":1,\"ship_to_po_box\":false,\"is_saturday_delivery\":false,\"ship_complete\":true,\"is_home_business\":false},\"total\":15.71,\"discount\":0.0,\"subtotal\":8.54,\"shipping_charge\":6.25,\"offshore_surcharge\":0.0,\"saturday_shipping_surcharge\":0.0,\"saturday_shipping_surcharge_for_ship_method\":15.00,\"oversize_surcharge\":0.0,\"weight_surcharge\":0.0,\"international_processing_fee\":0.0,\"sales_tax\":0.92,\"sales_tax_label\":\"Estimated Sales Tax\",\"purchase_order_number\":null,\"promotion_code\":\"\",\"device_data\":\"{\\\"device_session_id\\\":\\\"${sessionId}\\\",\\\"fraud_merchant_id\\\":\\\"600000\\\"}\",\"is_promo_code_valid\":false},\"sop_number\":\"\",\"security_code\":null,\"rc_order_form\":\"\",\"o_checksum\":\"${o_checksum}\",\"rc_checksum\":\"${rc_checksum}\"}","payment":{"payment_type_id":0,"credit_card":{"nonce":"${creditCardToken}","expiration_month":"03","expiration_year":2019},"paypal":null}}

Seems like JMeter converts \\\"device_session_id\\\" to \\"device_session_id\\" (with the latter being invalid JSON).

Please let me know if you need more information. Sorry about the big wall of text.

Thanks,

Do you mind providing a simple .jmx file or Results Tree script so I can replicate this myself? I feel I can help fix this if I'm able to replicate what you are experiencing. Having trouble understanding based on your post alone
