in my Angular 13 project I have a npm dependency which has fesm2020 and fesm2015 module: see package.json
"module": "fesm2015/ds-components.mjs",
"es2020": "fesm2020/ds-components.mjs",
"esm2020": "esm2020/ds-components.mjs",
"fesm2020": "fesm2020/ds-components.mjs",
"fesm2015": "fesm2015/ds-components.mjs",
when i serve the angular project, the fesm2020 module is used. After lots of debugging I found out that the fesm2020 module has strange behaviour but the fesm2015 module would work. How can I tell angular to use the fesm2015 module instead?
