Trouble with hmac verification for multiple bulk actions: any solutions?

Thank you for this thread. However, this isn’t working for me even when I turn:

hmac=d0891aa4b5b829eb515914624ff2242f859e671e23784d45cb6337e50c5e2788&host=Zmp0ZXN0aW5nMi5teXNob3BpZnkuY29tL2FkbWlu**&ids%5B%5D=6579882721444&ids%5B%5D=6579882786980**&locale=en-US&session=5bb5bac200df59c2963f405f7a0a25d52afcb36933057c669dbb45b6f942bd27&shop=fjtesting2.myshopify.com&timestamp=1645475039

I’ve tried sticking the ids array at the end as well, no joy. Any idea what I’m doing wrong? Thank you.
