Failing to specify prior for `sds` class

Interfaces brms

I have tried to specify a prior for sds class in several ways, but the error message is that the prior does not correspond to any model parameter. For example, I have tried:

prior(normal(0, 1.0), class=sds, coef="s(Items, bs=\'re\'")

which is exactly what the prior_summary() specifies. Then, I’ve also tried:

prior(normal(0, 1.0), class=sds, coef="s_Items")

prior(normal(0, 1.0), class=sds, coef="s(Items)")

Nothing works. Please help!
