can you show us the whole error and the request you've made?

#

Like the error says, you need to append data either as a string, a buffer, or a Unit8Array

function where I am forming the form data async sendEmailWithAttachment(data:any, templateId:string,fileData:any) { if (!this.configService.get<boolean>('email.enabled')) { return null; } try { const formData = new FormData(); const fileOptions = { knownLength: statSync(fileData.filepath).size, filename: fileData.filename, }; formData.append( 'attachmentFiles', createReadStream(fileData.filepath), fileOptions, ); formData.append(`data["name"]`, data.name); formData.append(`data["from_date"]`, data.from_date); formData.append(`data["to_date"]`, data.to_date); formData.append("from",this.configService.get<string>('email.fromEmail')); formData.append("to", fileData.sendToEmail); formData.append("templateId", templateId); formData.append("requestId", fileData.requestId); formData.append("isExternalStorage","false")

            const headers = {
                ...formData.getHeaders(),
                'x-api-key': this.configService.get('xApiKey'),
                'Content-Length': formData.getLengthSync().toString(),
                'x-correlation-id':fileData.correlationId || uuid()
            }
            this.logger.log(`Generating email with payload: ${JSON.stringify(formData)}`);
            const response = await this.requestHelper.postCallTransactions(url, formData, headers, {});
            this.logger.log(`Equitas email generation response: ${JSON.stringify(response)}`)
            return response;
        } catch (err3) {
            this.logger.error(`Equitas generate email api failed with error: ${JSON.stringify(err3)}`)
            throw err3
        }
        
        
      }  ```

#

so it's just a runtime error, right?

warped matrix Dec 30, 2022, 3:09 AM

#

yes

copper gorge Dec 30, 2022, 3:13 AM

#

Seems like whatever you think you're sending, you aren't

warped matrix Dec 30, 2022, 3:19 AM

#

but same code works in dev enviroment but not in production

copper gorge Dec 30, 2022, 3:20 AM

#

So there's a difference in the code being ran

warped matrix Dec 30, 2022, 3:21 AM

#

only the url change in dev we use https and in production use http that is private
