RET191106 is an Error in JSON structure validation in GSTR 1.	The GSTN cannot recognise the JSON file you provided, or there are structural issues in the uploaded JSON file.	Make sure you include the GSTIN in the JSON file. Check that the uploaded JSON file is the most recent, correct on the GST Portal, and not processed with an error in gstr 1.
RET191113 means the GSTIN is invalid. Please provide a valid GSTIN.	The GSTIN specified in the JSON file differs from the one specified in the client’s GST account or GSTIN.	As you utilise the GST tool to build the JSON file, be sure the GSTIN you enter is right. Transform the GSTIN into a JSON file. Then, save it before uploading it to the GST Portal. Check if the customer’s GSTIN is legitimate.
RET191114 indicates that the invoice date is Invalid.	The invoice date cannot be before the registration date.	You must invoice after the GST registration date. You must modify the invoice type to B2C.
RET191115 – The invoice number does not exist. Please enter a valid invoice number.	The invoice must be at most 16 characters which will contain numerical / alphabets / special characters/hyphen/dash and slash, symbolised as ‘-‘ and ‘/’, and a unique combination for the financial year(FY ).	Ensure that all the invoices contain a GST invoice number. As per the GST rules, if there is no invoice number for an invoice, then assign one and create the JSON file again. If the invoice is invalid, the item must be deleted from the JSON and uploaded again.
RET191124 – Original Invoice is Invalid. Unfortunately, you cannot track the original invoice. Instead, enter the correct invoice number and date.

Check for no change in invoice data between what you uploaded and what you are now trying to upload. If the invoice is uploaded, avoid the error and do not make any changes. If you need to make the changes, you must first delete the old invoice on the government portal. Now upload the amended invoice with the corrected JSON file (rather than invalid JSON data).
