Hello, I would like to follow up with the thread which was closed already - it seemed like problem with sourcemaps was fixed, but it seems it isn't working 100%. > [@Uploading sourcemaps from AIX webserver](https://discuss.elastic.co/t/uploading-sourcemaps-from-aix-webserver/303526): > > Hello, I can't figure out how to upload sourcemaps to kibana. \*\*Config for APM\*\* // using full condition instead of PROD variable (webpack will remove this code if syntax is like this) if (process.env.NODE\_ENV === 'production') { window.amp = initApm({ // Set required service name (allowed characters: a-z, A-Z, 0-9, -, \_, and space) serviceName: `web-fe - ${window.location.hostname}`.replaceAll('.', '-'), // Set custom APM Server URL (default: http://localhost:8200) serverUrl… I have managed to get it working partially with help of elk team on this forum, but not all errors are mapped - sourcemaps are only working for specific errors. This is example of error that is not working 100%, but as you can see there are some sourcemaps ![image](https://us1.discourse-cdn.com/elastic/original/3X/b/4/b4144c2b94dbc086ab00b5087ba0bf217dac265a.jpeg) metadata: ```auto @timestamp @timestamp 2022-07-18T15:12:14.902Z agent agent.name rum-js agent.version 5.12.0 client client.ip 10.10.221.223 ecs ecs.version 1.12.0 error error.culprit javascript/utils/apiHelpers.js in requestDidEnd error.exception.message fetch failed with response: SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data error.exception.type Error error.grouping_key ba0e3dd950c5658c8f643321aebf1cdc error.id 8bc9accabfee7667f0e2276aac2d207d event event.ingested 2022-07-18T15:12:16.780Z message message fetch failed with response: SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data observer observer.ephemeral_id f56f977e-a379-4003-9883-1499b7c0bb07 observer.hostname mvafls1 observer.id c9ef030a-e37d-4442-9475-b1d0691fb8db observer.type apm-server observer.version 7.17.0 observer.version_major 7 processor processor.event error processor.name error service service.language.name javascript service.name mva-fe - dev-mva-lab service.version 108.0.0 source source.ip 10.10.200.201 source.port 47277 timestamp timestamp.us 1658157134902720 url url.domain dev.mva.lab url.full https://dev.mva.lab:8443/portal/gui/inv-file/523/detail url.original https://dev.mva.lab:8443/portal/gui/inv-file/523/detail url.original.text https://dev.mva.lab:8443/portal/gui/inv-file/523/detail url.path /portal/gui/inv-file/523/detail url.port 8443 url.scheme https user_agent user_agent.device.name Other user_agent.name Firefox user_agent.original Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:101.0) Gecko/20100101 Firefox/101.0 user_agent.original.text Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:101.0) Gecko/20100101 Firefox/101.0 user_agent.os.full Windows 10 user_agent.os.name Windows user_agent.os.version 10 user_agent.version 101.0. ``` This is error that won't map anything ![image](https://us1.discourse-cdn.com/elastic/original/3X/6/6/662377307b52caa42f2b44ec8c7a94f2ba66788b.png) metadata: ```auto @timestamp @timestamp 2022-07-20T08:55:26.202Z agent agent.name rum-js agent.version 5.12.0 client client.ip 10.10.221.223 ecs ecs.version 1.12.0 error error.culprit portal/gui/static/js/main.4f27a0f1.chunk.js error.exception.message fetch failed with response: SyntaxError: Unexpected end of JSON input error.exception.type Error error.grouping_key 49d842a4fd6feb84f7df6e3dd74525c4 error.id 38f8b6f00d8cc4b69e513a487f5e3803 event event.ingested 2022-07-20T08:55:26.876Z message message fetch failed with response: SyntaxError: Unexpected end of JSON input observer observer.ephemeral_id bb81d664-2185-473a-a9ca-57e6750534e6 observer.hostname mvafls1 observer.id c9ef030a-e37d-4442-9475-b1d0691fb8db observer.type apm-server observer.version 7.17.0 observer.version_major 7 parent parent.id a75d26fd4edea527 processor processor.event error processor.name error service service.language.name javascript service.name mva-fe - dev-mva-lab service.version 108.0.0 source source.ip 10.10.200.201 source.port 59207 timestamp timestamp.us 1658307326202587 trace trace.id efa6c3e74f6335023babf96071a7ef9d transaction transaction.id a75d26fd4edea527 transaction.sampled true transaction.type route-change url url.domain dev.mva.lab url.full https://dev.mva.lab:8443/portal/gui/inv-file/5334/detail url.original https://dev.mva.lab:8443/portal/gui/inv-file/5334/detail url.original.text https://dev.mva.lab:8443/portal/gui/inv-file/5334/detail url.path /portal/gui/inv-file/5334/detail url.port 8443 url.scheme https user_agent user_agent.device.name Other user_agent.name Electron user_agent.original Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Cypress/10.3.0 Chrome/18.3.0 Safari/537.36 user_agent.original.text Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Cypress/10.3.0 Chrome/18.3.0 Safari/537.36 user_agent.os.name Linux user_agent.version 18.3.0 ``` Any ideas ?
