Splunk sdk and vue.js conflic

Please help me trying to discover what is wrong here:

js/chunk-2e248a0e.3da32a73.js from Terser
Invalid assignment [/node_modules/splunk-sdk/index.js:21,15][js/chunk-2e248a0e.3da32a73.js:31187,222]

I tried diferent versions and imports but I cant find the conflict. 

-> vue-cli-service build --mode deploy and "splunk-sdk": "2.0.0" are conflicting 
"terser": "5.18.1"
