Hello @Anonymous,
Do you have any JS files in your tsconfig.json? What version of PBIVIZ do you use?

hello @v-viig,
No my Tsconfig.js contains only ts files:
".api/v1.7.0/PowerBI-visuals.d.ts",
"src/main.ts",
"typings/index.d.ts",
"src/dataTransform.ts",
"../jsFunctions/**.ts",
"../jsFunctions/styleTransform.ts",
"../jsFunctions/objectEnumerationUtility.ts",
"../jsFunctions/functions.ts"
Api 1.7
Looks like your TS is really heavy.
You might try to start node.js by using this command:
node --max-old-space-size=8192 PathTOPBIVIZ
