Stage 1 - Payment channel is not switching when intermediaries of one channel doesn't have sufficient funds in multi-hop payment channel

Nobody has claimed this yet.

Scenario: We were trying multi-hop payment from A to C
A opened a channel of 50000 satoshis with B (local balance: 40000, remote balance:0 with respect to A)
B opened a channel of 80000 satoshis with C (local balance: 70000, remote balance:0 with respect to B)
A opened a channel of 90000 satoshis with D (local balance: 80000, remote balance:0 with respect to A)
D opened a channel of 55000 satoshis with C (local balance: 45000, remote balance:0 with respect to D)
Available channels:
A -----> B ------>C
A -----> D ------>C
Now, C added an invoice of 20000 satoshis.
A----->D----->C channel was randomly selected for multi-hop payment
Balances was updated on A ------>D------->C
In A -----> D; A: 60000 and D: 20000
In D -----> C; D: 25000 and C: 20000

Again, C added an invoice of 30000

Expected result:
Now, channel A----->B----->C should be used to settle this payment because D doesn't have sufficient funds.

But we are getting this
{
"payment_error": "unable to route payment to destination: TemporaryChannelFailure",
"payment_preimage": "",
"payment_route": null
}

The report names no files, tests, or entry points. Reproduce the two-route scenario with the stated balances, then trace payment routing and channel selection; done means the second 30,000-satoshi payment uses A-B-C instead of returning TemporaryChannelFailure.
