TaskFactory fails without concurrency options argument

[basz]

This seems to generate an error for me with ember 3.28.9 and ember-concurrency 2.3.0

setupCompanyProfileTask = task(this, async (identity) => {

After migrating to the 'new' syntax I get these run time errors

Cannot convert undefined or null to object

Which are fixed by adding a concurrency options argument.

setupCompanyProfileTask = task(this, { drop: false }, async (identity) => {

after updating to 2.3.2 this issue was resolved too it seems.

setupCompanyProfileTask = task(this, async (identity) => {

that now works as expected

As I bumped into this same issue and a regular version update in package.json didn't help, I manually removed the entry for ember-concurrency@1.x, ... from yarn.lock, then ran yarn again and voilà.

Those references were "inherited" from addons like ember-bootstrap, ember-power-select and ember-power-calendar and were resolving to 2.2.1.

Ran into same issue... seems like updating is the answer, but if you can't update then passing an empty object as the second argument also works:

setupCompanyProfileTask = task(this, {}, async (identity) => {
