Parse xml request body using loopback4 - node.js

Question

I'm looking for an extension to existing body parsers.. I have a requirement to parse xml data using loopback4 node.. I have tried setting content-type to application/xml but it is giving me an unsupported content type error. xml is not supported. I did not find any examples in loopback4 documentation.
I have tried below code:
#post('/dashboard/parseXmlRequest/', {
responses: {
'200': {
description: 'parses the xml and sends the response',
content: {
'application/xml': {
schema: {
type: 'any'
}
}
},
},
},
})
async parseXmlRequest(
#requestBody({
content: {
'application/xml': {
schema: {type: 'object'},
},
},
})
data: object) {
try {
console.log("request : ", data);
return await this.myService.deviceResponse(body);
}
catch (err) {
console.log(err);
return err;
}
}
Can you please help.. thank you.

have you made any progress?
As workaround, I'm using text/plain instead xml;
#post('/data/import', {
responses: {
'200': {
description: 'Import XML',
content: {'application/json': {type: 'any' }},
},
},
})
async import(
#requestBody({
content: {
'text/plain': {
},
},
})
xml : string,
): Promise<string> {
return this.dataRepository.import(xml);
}
async import( xml: string) : Promise<string> {
try {
console.log("XML =>",xml);
const result = await xml2js.parseStringPromise(xml, {mergeAttrs: true});
const json = JSON.stringify(result, null, 4);
return json;
} catch (err) {
console.log(err);
return Promise.resolve(err);
}
}
