I am trying to use batch feature, I followed the example(https://github.com/Soontao/light-odata/blob/74d2d0cfe2f1285482f8f3ca763db51b7df9446a/docs/Batch.md) provided, but got error as below
TypeError: multipartBody.split is not a function
at parseMultiPartContent (XXX@odata\client\lib\batch.js:128:37)
at OData.execBatchRequests (XXX\node_modules@odata\client\lib\odata.js:408:56)
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

Please advise, thanks!

Hi @jessicali001

could you provide more information about your setup ? frontend/backend ? node version? did you use the customized fetchProxy ?

looks like fetchProxy does not return correct content then later parsing logic failed.

Theo

Hi Theo, Thanks for your email. I am using node version 18, it is a backend. I am not using customized fetchproxy. I am testing in Postman as below: [image: image.png] Function code is as below: export async function testBatch(req: Request, res: Response) : Promise<void> { console.log('Edit - Accessing data using OData Client') // get info from body const actType = req.body as ActType; console.log(actType); console.log('Executing batch!!!'); // execute request and return mocked responses const result = await client1.execBatchRequests([ client1.newBatchRequest({ collection: "ACAD_ACT_TYPES", entity: { ACAD_ACT_TYPE: 'testFixed2', }, method: "POST", // withContentLength: true, for SAP OData, please set this flag as true }), client1.newBatchRequest({ collection: "ACAD_ACT_TYPES", entity: { ACAD_ACT_TYPE: 'testFixed', }, method: "POST", // withContentLength: true, for SAP OData, please set this flag as true }) ]) console.log(JSON.stringify(result)); res.json({ code: 200, message: 'Successfully finished!' }); } in the app.js, app.post( '/testBatch', catchAsyncErrors(testBatch), ); Please advise, thanks! Regards, Jessica

Hi @jessicali001

sorry we cannot reproduce this in our odata service, could you try to manually create $batch payload and provide the response header/content to us.

we guess there are something not handled correctly for response.
